Performance Analysis of BER and SNR of BPSK in AWGN Channel

WebFrom Shannon’s theory, the SE of a single AWGN channel is given by the widely known relation [14,16], (1.1) SE ≡ C B = log 2 1 + SNR , where the SNR is defined as SNR = P / N where P is the average signal power and N is the average noise power in a bandwidth equal to the baud rate R s of a time-division multiplexed (TDM) signal. WebAdditive white Gaussian noise (AWGN) channel without fading. A worst-case scenario is a completely random channel, where noise totally dominates over the useful signal. This results in a transmission BER of 50% (provided that a Bernoulli binary data source and a binary symmetrical channel are assumed, see below).
