Python Code for BPSK BER in Rayleigh Fading July 10, 2017 BER Performance, Fundamentals BER, BPSK, Fading, Python We have previously calculated the bit error rate of BPSK in an AWGN channel, we now do the same for a Rayleigh fading channel. 0, the error rate is computed using diversity. In the above example, the Rayleigh Fading is modelled as a single tap filter, meaning that there is only one path from tranmitter to the receiver. For both the cases, we consider a simple flat fading Rayleigh channel (modeled as a single tap filter with complex impulse response h). I remember it by remembering the basic AWGN channel.
