BPSK BER v/s SNR Simulation for AWGN channel

Binary Phase Shift Keying Simulation for BER v/s SNR of Additive White Gaussian Noise Channel



View License

Transmitted bits at the receiver are detected using SOFT Detection Technique, i.e. if the received bit is positive it is detected as +1 and if the bit is negative it is detected as -1. AWGN with mean 0 and variance 1 is used at the receiver. If the transmitted bit is -1, it is received as -(sqrt(P))+n, where n is Gaussian Noise and P is signal power. As noise is having 0 mean, -sqrt(SNR) is used instead of -sqrt(P). Similarly if the transmitted bit is +1 then it is received as +(sqrt(SNR))+n.

Thx for sharing and being us familiar with those kind of applications.

Some clarification on the detection scheme used has been given.
