Simulation of CDMA Communication System Performance

This MATLAB source code implements a comprehensive simulation of CDMA communication system performance. The program includes generation algorithms for direct sequence codes, frequency hopping patterns, time hopping sequences, along with M-sequences and Gold sequences using MATLAB's communication toolbox functions. The simulation calculates bit error rate (BER) performance under both AWGN (Additive White Gaussian Noise) and Rayleigh fading channel conditions, incorporating appropriate modulation schemes and channel models. The code structure allows for easy extension to include additional features such as channel estimation algorithms, interference cancellation techniques, and multi-user detection methods to further enhance system performance and accommodate various application requirements. The implementation demonstrates key CDMA concepts through practical MATLAB coding approaches suitable for both educational and research purposes.
