I think the noise amplitude calculation should be:
10^(-snr_db/20.0), but the code has: 10^(-snr_db/10.0)
It looks like all the transmitters scale to an average magnitude squared P_avg=1. Then SNR_lin = P_avg/sigma^2, so sigma^2 = 1/snr_lin = 1/(10^(-snr_db/10)) => sigma = sqrt(1/(10^(-snr_db/10))) = 10^(-snr_db/20). The dynamic channel model takes in the standard deviation not the variance.
What am I missing?
