cdma synchronization

[zainabmaghraby]

hi all

i'm master student and aim to introduce new spreading code in cdma systems and need to test this sequence in a cdma system to approve the spreading code 

all what i need is a simulation for CDMA system in labview to modify it and replace the PN or gold sequence with my new spreading code 

can i find an example of that 

thnx

Hello!

The easiest way to use a CDMA system in LabVIEW would be to use the RFmx WCDMA driver to create the WCDMA waveform. You can then load it into LabVIEW and play it back using the RFSG Playback Library. With this method, you will be able to create and modify your CDMA waveforms and programmatically view them in LabVIEW.

thnx very much for ur help

i would add another question ...which is can i use it with USRP? instead of RFSA and RFSG?

Appreciate this is a little late now, but in case anyone else is wondering!

Short answer, Yes! As long as your using RFSG API that don't actually reference the RFSG hardware, you can use the RFSG VIs with USRP.

In this case the niRFSGPlayback Read Waveform From File just reads a file, and outputs a waveform!
