Sorry but have you found any Matlab code regarding fast fading Rayleigh channel?
Now I'm trying to simulate BER performance of BPSK with time-variant Rayleigh channel with different Doppler freqs!
I want to simulate BER performance using Clarke fading channel model with several Doppler freqs in detail. Thanks in advance!
Simply use Rayleighchan function in MATLAB, decide the speed of your receiver, get the corresponding doppler frequency = (v(speed)/c(light speed))*fc (carrier freq) and set it as an argument.
