I would like to run the QPSK at 13.56 MHz of carrier frequency. Any one have a matlab code please send me one. I have tried to write this code but did not work at 13.56 MHz. Wont know what wrong is my code?. In my code, I write the carrier at 13.56Mhz and sampling frequency at 120KHz. When I take FFT of signal it always show at 40KHz. I would like to show FFT at 13.56 MHz. Any one have know about QPSK please let me know or if you have a code it is really appreciated. Thanks
