Hi
I have simulated a QAM modulation in AWGN and I want to compare my result (e.g; BER vs. SNR) with a reference to be sure of my detection accuracy.
Can you introduce me a reference.

Proakis' figures are : BER vs. Eb/N0 as well as MATLAB BER Tool.
I have defined SNR as : the ratio of the power of signal to power of noise at the receiver.
 

ber vs snr

simply scale your SNR and then compare to Proakis's.

SNR = Eb/No * 2 for 4QAM
 

snr qam

Hi,

S/N = (Eb*Rb)/(N0*Bt) and Bt = Rb/log2(M)

=> S/N = Eb*log2(M)/N0

Best Regards
