## i need matlab for this system dynamics

a random Rayleigh flat-fading channel object based on Jake?s model is generated in matlab with sampling period of 10 μs and the maximum Doppler shift is set to 200 Hz. The additive white Gaussian noise with snr of 23 dB is used. The required ber is set to 10−3 and the average (...)

## Relation between BER & SNR for BPSK

for BPSK, the probability of error, ber = Q(sqrt(2Eb/No)) where Eb/No is the absolute snr per bit (not dB) and Q(X) is the common Q-function (area under Gaussian for x>X) Hope it helps
