- BER of BPSK in AWGN Channel
- License: Freeware
- Price: 0.00

The MATLAB program simulates binary phase shift keying (BPSK) at baseband through Monte Carlo method. The goal is to simulate bit error rate (BER) over an additive white Gaussian noise (AWGN) channel. For realizing that, the effect of noise is represented in the baseband with Gaussian random samples added to each signal sample.
