BER performance of AWGN channel

Provides a simple BER analysis of BPSK modulation in AWGN channel and Rayleigh channel. AWGN channel includes only noise and considers only a single path channel. i.e There is no fading due to multipath situations. Ideally, this channel doesn't exist as wireless communication is bounded to have mult...
