A four-user spread spectrum communication system with spreading gain N=16, employing Walsh codes for direct sequence spreading, BPSK modulation, and AWGN wireless channel. The receiver performs despreading, demodulation, and decision making. Through MATLAB simulation, we obtain bit error rate versus signal-to-noise ratio results for one user, implementing correlation detection and threshold comparison algorithms.
