How to convert a baseband signal with bandwidth 20MHz to an RF signal with center frequency 2.4GHz and the same bandwidth 20MHz

Hi,
I was wondering how to convert a complex baseband signal with bandwidth 20MHz to an RF signal with center frequency 2.4GHz and the same bandwidth 20MHz in simulation. I tried
1. Multiplying the complex double type baseband signal (1-D array) by exp( j * 2 * pi * 2.4E+9 * T ) where T is the symbol period of baseband signal.
2. Usage of MT upconvert baseband but doesnt keep the BW constant
Looking forward to your help.

I should add that you can multiply your baseband signal with two carrier signals that are shifted by 90° and then add or subtract the result to obtain upper or lower sideband only. You can try to search about IQ moduilators/demodulators to learn more.
Cheers
Edgar

TS3212 It starts to load just fine, but at about 26-32% done it just stops with no information or errors, I have tried to download several times, and the same thing happens?

Is there a way to get your playlists if you no longer have a PC/computer. But now have an iPhone, I can not reload iTunes to my PC and purchashed an iPhone to get my songs but was only able to retrive the songs I had purchased not all the songs in the library.

Try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?
If you can't get a working installer via the standard download links, try the following download links instead:
iTunes 11.1.4 for Windows (32-bit) - iTunesSetup.exe
iTunes 11.1.4 for Windows (64-bit) - iTunes64Setup.exe

I have Photoshop Elements 9 on an iMac with OS 10.6.8. I bought a new printer/scanner and the program will not import the new scanner to replace the old one. How do I do this?

Thank you for your suggestions. I downloaded a more recent version of Twain, but this didn't help. I also tried closing and opening Photo Shop and restarting my computer without success. Reinstalling Photo Shop sounds like a very promising solution, but I'm not sure I will do it. In the meantime I can scan items using a printer program. These scans open in Photo Shop. It is an extra step.

I am using duel thunderbolt displays with a MacBook Pro. I only have the option to have sound come from one or the other. Has anyone thought of making the left channel come from both speakers on the left Monitor and the same of the right? If yes, how is that done? The MacBook Pro could even be a center channel if configured in that order.

See the following thread on the same topic:
2 Thunderbolt displays MBP = sound coming from both displays?

Dude or hot-spur,
Not fishy at all!!!! You really think I would have taken any more of my time to post a bogus rant? We'll no, it is unfortunately all true. I want to hear from anyone who is experiencing such problems not anyone else that wants to put there two cents in. I really don't need anymore hate or negativity. Just people's experiences because I feel like I am the only one having so many problems. Thank you
Yes, I have had some unfortunate bad luck to have so many problems at the same time, but some of them are just things you cannot do on the new OS.
Thank you again

When I sync my phone I get my husbands phone contact list, apps etc and the same happens when he sync his phone. It recognizes our phone as different users. How can I get it to not do that??

When I sync my phone I get my husband's phone contact list, apps, etc and the same happens when he syncs his phone. It does recognize our phones as different users so how can I stop this from happening when we sync?

Did you tick the box in iTunes to sync with the Mac address book? Are you using the same user account on your Mac, with the same contacts in the same address book?

I just did the recent upgrade and now I keep getting an error message when I try to open a book on my Kindle app, I have deregistered the app and reloaded and the same thing happens, does anyone know how to fix?

You are seeing the message because the new AirPort Extreme has some specific System Requirements:
http://www.apple.com/airport-extreme/specs/
Setup and Administration
iPhone, iPad, or iPod touch with iOS 5 or later and AirPort Utility 1.3
Mac with OS X Lion v10.7.5 or later and AirPort Utility 6.3
AirPort Utility 5.6.1 in Snow Leopard may or may not work correctly with the new Extreme for all functions. As long as things are working OK for now, you can probably leave them "as is" and wait for another Mavericks update to fix some issues before you "upgrade".
If you have an iPhone or iPad, you could use that to administer any settings changes on the new Extreme.

HT1296 upon syncing my ipad with my mac, the process reversed and sent pictures back to the ipad on the camera roll. Now none can be deleted. There is no trash showing up, only edit. Instead of the 900 pics in the photo stream, and the same in photos

I canot delete pics from my photos on ipad. During synching process to my mac the pictures started to suddenly be downloaded back to the ipad. I now have 900 pics in photos and the same in photo stream on the ipad. There is no trash can, only an "edit" choice.

There are 9 different versions of iPhoto and they run on 9 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Include things like:
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For example, if you have a problem with exporting, then explain by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted? - Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have.

I have bought itunes songs on an ipad with my daughter apple id. i would like to back them up on the same computer I sync my iphone with using my apple id but they will not transfer. Both iphone and ipad have only been synced on the computer mentioned since they were purchased. Is there any way to get the ipad music transferred to the computer?

And they were definitely purchased from the iTunes store, they show on the account's purchase history (Store > View Account on a computer's iTunes, or you can view the last 90 days purchases via http://reportaproblem.apple.com) ?
You could potentially log into the account on that computer's iTunes (Store > Sign Out to log out of your account, that will then change to a Store > Sign In option) and redownload them by clicking on the id towards the top right of the iTunes screen and Purchased on the popup :
But that will potentially tie that computer to that account for 90 days : Manage your associated devices in iTunes - Apple Support
Or do you have a different computer that you could redownload them on and then copy them over to that computer via a flash drive or memory card, and then add them to its iTunes via File > Add To Library ?

I'm attempting to sync several albums from itunes to iphoto. When select to sync all albums it copies over the previous recorded album. I tried to sync the Albums individually and the same thing happens. Any ideas on how to sync my albums?

Hi NWL1,
Thanks for the question. If I understand correctly, the iPhone won't update and is stuck. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.
If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support
Thanks for using Apple Support Communities.
Have a great day,

With previous editions of iTunes for Windows, I could play a CD at the same time as it was being imported. That does not work anymore. Why not, and is there a way to do both with the most current version?

With previous editions of iTunes for Windows, I could play a CD at the same time as it was being imported. That does not seem to work anymore. Why not, and is there a way to do both with the most current version? I am running a Surface Pro 2 with Windows 8.1 and the most recent vesion of iTunes, which, in all other respects, works well. I just can't listen to an album for the 1/2 to 1 hour that it takes to import it into my library.

Two JVM's ? I thought that J2EE worked within a single JVM and run everything in containers. Can you see the two processes?

You may need to replace the Pram battery.

Imported album to itunes library but it will not sync to my ipod, tried with my husbands ipod and the same thing. What could be the problem?

imported an album to my itunes library, but it won't sync with my ipod classic. I tried it with my husbands ipod also and the same problem. What could be the problem?

Thank you all for your replies. Here is what i ended up doing. I cannot afford any 3rd party software so i went to itunes and manually entered all my playlists. As I had indicated my purchased music was on my new computer just not the playlists and I could not sync my ipod. After I rebuilt all my playlists I tried to restore my ipod to factory defaults/new. All of the steps called for in apple support and elsewhere were not available to me. I connected my ipod, went to my computer, right clicked my ipod, and formatted. That wiped my ipod so when I connected to itunes it then gave me a restore option. I did the restore and all is good in the empire again. I can now buy new music and sync my ipod so I am a happy camper.
Thanks to all.
