this is the QAM modulation and demodulation tech. with speech example
Watch this File
you can rum these files by my_speech.m file, taking an value like my_speech(64, 'qam') in the command window of MATLAB.
this code is not working on command window.. even in R2011b version.
In addition, the quam modulator doesn't work for M=2,8,32 i.e., for odd powers of 2..!! Really needs some correction!
I tried with my own file sound but it doesn't work
What do I do?
