Hello everyone,
I am kind of a novice in MATLAB. I have been trying to perform QPSK modulation of an .mp3 / .wav file and then pass it through an AWGN channel. Can anyone please tell me how to go about this process? Thanks in advance.

sounds like an assignment problem. anyway... 1. read file using wavread() 2. use modulate() to apply QPSK modulation 3. use awgn() to add noise with a desired SNR 4. use demod() to obtain the received signal.
