wave file input to psk demodulator

[madd]

Hello

I have a QPSK modulated wave file in Matlab i want to demodulate it in PSK demodulator.vi of Labview modulation tool kit example how can i do that. in the example we have Bit pattren genarator .i dont have bits i have this wave file(having specs like  Fc, symbol rate e.t.c) number.also how would i listen to my wave file signal after demodulation mena i want to make an other wave file tohere what i have demodulated.

Regards

Hi Madd,

My impression from your message is that this is no ordinary .wav file.  The PSK demodulator.vi requires that you input a complex waveform containing the data, PSK system parameters, filter coeficients, and synchonization parameters.  If you can find the relavent information in the QSPK file you can read in that information and input it to the PSK demodulator vi and it should work fine.  Without more information about the file format, it would be difficult for me to offer anymore suggestions.  I'm assuming you could use a read binary vi in labVIEW and take the relavent binary data and convert it into the parameters you need.

I hope this helps,
Paul C.
