A direct sequence spread spectrum communication system with interference, where PN codes are generated using m-sequence generators and transmitted through an additive white Gaussian noise (AWGN) channel. The received signal at the receiver comprises "useful signal + AWGN + interference." The system performs despreading and decision operations to recover user signals. Key implementation aspects include generating m-sequences using linear feedback shift registers (LFSRs), implementing correlation-based despreading algorithms, and employing threshold detection for signal decisions. The system demonstrates bit error rate (BER) performance versus Eb/N0 ratio under different spreading gains (10, 30, 50), showing how processing gain affects interference rejection capability.
