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.

This experimental report elucidates the principles of wireless communication system simulation, focusing on two primary tasks: performance comparison of BPSK modulation over AWGN and Rayleigh channels, and analysis of CDMA spread spectrum multi-user systems. The report details fundamental theories and includes commented MATLAB source code in the appendix, demonstrating practical implementation using communication toolbox functions for modulation, channel modeling, and BER analysis.

This study implements BER (Bit Error Rate) comparison for 2x1 (MISO), 1x2 (SIMO), and 2x2 (MIMO) configurations using BPSK modulation. The MATLAB simulation evaluates diversity gains through signal transmission/reception combinations, demonstrating performance improvements through spatial diversity techniques and maximum ratio combining algorithms.
