Detailed Documentation

This research conducts comprehensive simulation studies on DS-CDMA (Direct Sequence Code Division Multiple Access) systems, primarily analyzing the system's bit error rate performance under multi-path fading channel conditions. The implementation involves generating orthogonal spreading codes using Walsh-Hadamard sequences and simulating Rayleigh fading channels with multiple propagation paths. Key algorithmic components include: - PN sequence generation for spreading and despreading operations - Rake receiver implementation with maximum ratio combining to mitigate multi-path effects - BER calculation through Monte Carlo simulations with varying signal-to-noise ratios The study further explores performance enhancement techniques such as power control algorithms, advanced channel estimation methods, and interference cancellation schemes to improve overall system robustness and transmission quality.
