Direct Sequence Spread Spectrum Communication System

This documentation provides the main program and subprograms for simulating sinusoidal interference suppression in Direct Sequence Spread Spectrum (DSSS) communication systems across different Signal-to-Noise Ratio (SNR) conditions. DSSS is an advanced communication technique that enhances signal quality by spreading the signal bandwidth. The simulation employs various SNR settings to replicate real-world communication environments, with the main program coordinating system parameters and the subprograms handling specific functions like PN sequence generation, modulation/demodulation processes, and interference cancellation algorithms. The simulation results help analyze system performance metrics including bit error rate (BER) and interference rejection capability, providing practical guidance for real-world implementations. Key functions include correlation-based detection, adaptive filtering techniques, and SNR-based performance evaluation modules.
