Creating complex data waveform

Hi,
I have a 2 channel audio file that contains both the real and complex parts of an I/Q wave. I am trying to demodulate this using the MSK block from the modulation toolkit but I have trouble getting the I/Q stream in the right type. The MSK block asks for a complex waveform as input but after building this complex waveform I found out that it really needed a 'Complex Data Waveform.ctl'.
How can I get my data in the right format? I can't find a block that generates this 'Complex Data Waveform.ctl'.
I have attached a picture of the situation.
Best regards,
Jan

Okay, what you suggested allowed me to wire up the complex signals to the MSK block without, but I don't think the complex data is transferred correctly to the Complex Data Waveform.ctl. Running this leads to an error message (21837, not found in the explain error help page) stating a possible reason: 'Waveform contains no values'.
I've put an image with the setup in the attachment.
Thanks for all your help

  • Complex data type to application service create method(CRUD)(Urgent)

    Hi Experts,
    I have created an entity service with remote persistency(Web service).i am mapping the entity service CRUD methodes to web service methodes and i am calling these CRUD methodes form the corresponding applicaion service CRUD methodes.With out complex data types both sevices are working  fine.I have tested them in the service browser.
    Later I have created a complex data type in the entity service and mapped it to web service.But when i am creating the application service create(CRUD) method for this entity service the complex data type which i have created in the entity service is not being shown as possible input attributes of the application service create method.Due to this i am not able to pass this complex attribute form the application service create method to the entity service create method.
    Plz tell me how can i resilve this issue.(Urgent)

  • Creating Web service for PL/SQL Procedure with Complex Data Types

    I need to created web service for PL/SQL Procedure with Complex Data types like table of records as parameters, how do we map the pl/sql table type parameters with web service, how to go about these?

    Hello,
    When you are creating a service from a Stored Procedure, the OracleAS WS tools will create necessary Java and PL wrapper code to handle the complex types (table of record) properly and make them compatible with XML format for SOAP messages.
    So what you should do is to use JDeveloper or WSA command line, to create a service from your store procedure and you will see that most of the work will be done for you.
    You can find more information in the:
    - Developing Web Services that Expose Database Resources
    chapter of the Web Service Developer's guide.

  • Can "SPML Web Service Complex Data Type field" take multiple values ?

    In Generic Technology Connector's -SPML design parameters section, Can we give multiple values in SPML Web Service Complex Data Type field?
    If not, how can i call methods directly instead of calling them through a values of the "name" attribute of the "complexType" element in SPML Web Service Complex Data Type?
    I need 'SPML Web Service Complex Data Type' to hold multiple values.And based on the request it has to initiate appropriate method of action.
    Presently i have three methods add,modify and delete which i am calling through a single value of the "name" attribute of the "complexType" element in SPML Web Service Complex Data Type.
    I want to replace this single value with multiple menthods , so that a direct interaction between the method,OIM and target can be established.

    You'll need to create your own interface to the webapp database for those kind of data operations
    by this, are you speaking of the internal BC database which stores web app schema data? That would be great if it were possible to update that programmatically because I need to use the List (Checkbox List) field type (for the search functionality), but I need to supply the checkbox options from a web app rather than by manually updating the list entered in the Fields view of the web app settings (shown below).
    I'm curious if anyone else has tried this?
    Again, my reason for needing to use the List (Checkbox List) field type is that the page which processes searches knows to expect a comma separated list for this field type and then appears to be parsing out the individual values for searching out web app items with 1 or more matching values. You're right that text fields (string and multiline) just check for 'string contains' matches, and this would be ok if I was only ever needing to search just one value at a time. Here's an example of what I might do:
    Web App item field value (as recorded against the List (Checkbox List) field type:
    8294877,8294878
    Web App Search value (for this same field):
    8294879,8294877,8294885
    The search would return this web app item because the field contains 2 (1 or more) individual values even though they were entered into the search field in a different order. If this web app item were just a Text (string or multiline) field, the searched value is not a substring of the web app item's stored value, so it would not find a match. Hence the need to use Checkbox List field type.
    The web app will have thousands if not 10s of thousands of records, so dumping them all into one big array or object and searching on the front-end won't be practical (though it works great on smaller datasets).

  • Flex datagrid with complex data item - drag doesnt start sometimes

    Hi,
    my project has a datagrid which is rendering complex data item. I need to drag one row from the grid and drop it into the same grid but in a different position.
    I have enabled drag, drop and dragMove.I am able to drag and drop the rows. The problem is that sometimes the drag doesnt start.
    Here are a few scenarios where drag doesnt start
    the first column is not editable. if I start my drag by doing a mouse down on the frist cell of the row, it usually drags an empty row but sometimes it drags the whole row.
    if I have dragged and droped a row in position i(say). Then sometimes the row at position i-1 or i+1 doesnt get dragged no matter how many times i try to do mouse down and drag. However, if I drag some other row (not necessarily drop it elsewhere) and then try this row, it works.
    any pointers would be helpful.
    thanks in advance

    Update on item 4a -
    This was a major issue (the main reason for opening this thread really) and I managed to resolve it!
    As part of my application, I override the default DataGrid behavior for column selection (headerRelease event).
    Instead of sorting, I change the column's header looks and define it as Selected (for showing its dynamic properties and enable its deletion).
    At first I did this by setting styles, but the look didn't refresh unless I created a new instance of the header renderer.
    Later I changed thi behavior to work with states, but I left the new header renderer instance creation commands and those lines created all the mess!
    Conclusion -
    If you define a custom header renderer for your datagrid column and then a custom item renderer, don't create a new instance of your header renderer!
    It would still be nice to get some response for the other issues I raised.
    Thanks and have a nice week.

    After you create the partner link and the invoke (to create the variables), change the element type of the response message to the complex type definition of your collection that appears in the XSD. You can do the same thing if you want to change the element type of the payload of the request message as well.

             for (Object p : portTypes.values()) {

  • Consuming an ASP web service which responds with complex data types...

    Here's my problem - I'm trying to consume a web service from a provider that uses complex data types.
    The starting part of the WSDL looks like this (I've not included the whole thing) - named have been changed to protect the innocent:
    <wsdl:definitions targetNamespace="http://domain_name">
    <wsdl:types>
    <s:schema elementFormDefault="qualified" targetNamespace="http://domain_name">
    <s:element name="Authentication">
    <s:complexType>
    <s:sequence>
    <s:element minOccurs="0" maxOccurs="1" name="Username" type="s:string"/>
    <s:element minOccurs="0" maxOccurs="1" name="Password" type="s:string"/>
    <s:element minOccurs="0" maxOccurs="1" name="Token"/>
    </s:sequence>
    </s:complexType>
    </s:element>
    <s:element name="AuthenticateResponse">
    <s:complexType>
    <s:sequence>
    <s:element minOccurs="1" maxOccurs="1" name="AuthOK" type="s:int"/>
    <s:element minOccurs="0" maxOccurs="1" name="Token"/>
    </s:sequence>
    </s:complexType>
    </s:element>
    Since it's a complexType return, with a sequence, I'd expect an array or structure returned, but instead I just get the "AuthOK" value, and no way to get anything else.
    Here are the ways I've tried calling it:
    <cfscript>
        WS = createObject("webservice", "https://WSDL_URL");
        WS_ret = WS.Authentication(Username = "username", Password = "password", Token = "");
    </cfscript>
    <cfdump var="#WS_ret#" />
    <cfinvoke webservice="WSDL_URL" method="Authentication" returnVariable="WS_ret">
        <cfinvokeargument name="userID" value="7253320" />
        <cfinvokeargument name="password" value="ctpjxs3" />
        <cfinvokeargument name="SecurityToken" value="" />
    </cfinvoke>
    <cfdump var="#WS_ret#" />
    Any ideas how I can get the other variables in the sequence? I have other calls after this that have a much larger amount of variables, and as such I can't use it without being about to get more of the

    Thanks for the reply.
    If I CFDUMP the variable it returns just "1", no XML tags, nothing at all around the data - according to the web service providers they say that they are supplying the Token part as long as the first variable is "1" (a logical true if the authentication passed). If it is "0" then no Token is returned, that is why it's optional.
    As for the CFdocs issue, look here:
    http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=webservices_25.html
    The paragraph before it (about 2/3 down the page) states:
    In this example, the operation updateEmployeeInfo takes a complex type as input and returns a complex type as output. To handle the input parameter, you create a structure. To handle the returned value, you write it to a ColdFusion variable, as the following example shows:
    It even states that you call "updateEmployeeInfo", and nowhere mentions "echoStruct" as a method - it's seemingly been put in as a random method name, or a function call for something else. The WSDL above the example only mentions "updateEmployeeInfo" and "updateEmployeeInfoSoapOut", again not mentioning "echoStruct".
    I see this as an error in the docs as it's calling a non-existant entity in the WSDL, which should cause a run-time error.

  • Create Complex Web Service using ADF BC Service Interface

    Hi,
    We have a requirement to create a number of web services with complex data types. The data types model a logical database entity and therefore contain multiple "rows" of data.
    In the most simple example, we have an entity Person and Person Address where 1 person and have multiple person addresses. We need to create a web service that encapsulates these entities and the relationship. For example the web service payload would contain:
    +<Person>+
    --<firstname/>
    --<lastname/>
    --<dob/>
    --<sx/>
    --<address>
    ----<line1/>
    ----<line2/>
    ----<postcode/>
    ----<country/>
    --</address>
    +</person>+
    We have created ADF BC components for each entity and the relationships. Now we are attempting to use the ADF BC Service Interface functionality to expose web service methods that would create and update the underlying VO/EO/Database tables with one call (i.e. create a record in table Person and one in Person Address).
    Creating a service interface for each entity VO works fine but we require a complex service encapsulating the logical entity of Person.
    Does anyone know if this is possible with ADF BC Service functionality? Or should we be looking for alternative method of generating these web services?
    Any advice greatly appreciated.

  • Complex data polymorphism with functions

    Hi Labview forum,
    I just came across several bugs in my VIs processing of complex data.
    I created the VIs with real data as inputs and outputs.  Then later wanted to use them with complex data input.
    I think the VI threw away the imaginary components of my data.  Can some one confirm this is labview's behaviour?
    Now the question is, can I make VIs which recognise whether the input and operational output is real or complex and treat it as such?  Or should I set all my data types to be complex unless I know for sure they will be real.  The indicator displays don't look so nice when there are a whole series of +0i's.
    Regards,
    Jamie
    Using Labview version 8.0

    Jamie,
    You are correct in your first statement that LabVIEW "throws away" the imaginary components of your data if you connect a complex data type to a real number indicator (i.e. UINT8, 16, etc). You can tell that a transformation is occuring because a coercion dot appears at the corresponding terminal on the block diagram.
    One method to recognize whether or not the input data is complex is to use a case statement to determine if LabVIEW should treat/display the number as complex or real. I have attached a quick sample example that implements this design.
    One note with the code within the case statement is that it uses references to the indicators and property nodes to make the correct indicator visible. To see more information on this feature consult the LabVIEW help documentation.

  • Working with complex data types in web services ...

    Hi All,
    I have created a webservice and created an interface for that in ADF. Now as my web service returns a complex data type, i followed the steps given in this article "http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html" and it works fine, my results also get displayed. But only issue is i get a warning "JBO-25009: Cannot create an object of type:java.util.calendar with value:2008-09-23T23:51:30.000+05:30" and if i replace all the java.util.Date with oracle.jbo.domain.Date then i get a warning "JBO-25009: Cannot create an object of type:oracle.jbo.domain.Date with value:2008-09-23T23:51:30.000+05:30". Now i am unable to understand this although i believe it is a data type mapping issue, but not sure how to rectify it.
    Anybody knows the wayout?
    Regards
    Lokesh

    Andre,
    Thanks for youe response. I also tried makeing data type as string in place of date in data control.xml and it worked fine. So it confirms that i am facing with exactly similar issue as yours.
    I tried solution 2 mentioned in Frank's mail but its not helping[in fact i am already using web proxy as i am delaing with complex data types]. I created a web proxy and in java bean i placed break points to check the control flow[in order to check the root cause] but control never reaches the java bean!! I am not sure about the cause for it...control should pass through java bean isn't it??
    I am quite new to SOA...so can somebody just elaborate on how to rectify this using web proxy. I have been using this rl "http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html" to work with web proxies" to work with proxies.
