You can have a look at 16QAM demodulator code @ http://www.dsplog.com/2007/12/09/symbol-error-rate-for-16-qam/ http://www.dsplog.com/2008/06/05/16qam-bit-error-gray-mapping/ Good luck. @Jules: Maybe your 16QAM demodulation is the culprit?

I have simulated 4-QAM, 16QAM under AWGN and 4QAM under rayleigh fading and got good results. but when I simulate the 16QAM under rayleigh fading the decoder (MLD) hardly decodes even up to 50dB (BER=0.08102). Can anyone tell me what I'm doing wrong? because I'm only adding coefficient (y = h*x+n) Thanks hi!
