We issue the North America and International rig counts as a service to the industry. where SNR =Eb/N0*(Rb/W) Where Rb/W is the number bits per symbols for 8-PSK. 3, for M-PSK and M-PAM through the AWGN channel, we can see that the BER is minimal when the M-file is 2, and the BER is progressive as the M-file is increased. It means that Ber is fixed or 0. You should take this into account: awgn assumes the signal has unit power; the SNR argument of awgn is in dB; SNR is estimated as power of signal divided by power of noise, or approximately power of noised signal divided by power of noise. This function generates noise with unit variance and zero mean.
