A four-user spread spectrum communication system with spreading gain N=16, employing Walsh codes for direct sequence spreading, BPSK modulation, and AWGN (Additive White Gaussian Noise) wireless channel, achieving bit error rate vs. signal-to-noise ratio simulation results through despreading, demodulation, and decision processes at the receiver.
In-depth simulation analysis of bit error rate variations under different spreading gains and sinusoidal interference conditions
Design a single-user spread spectrum communication system with spreading gain N=16 using Walsh codes for Direct Sequence Spread Spectrum (DSSS), BPSK modulation over AWGN channel. The receiver performs despreading, demodulation, and decision operations. Simulation results show bit error rate versus signal-to-noise ratio performance for one user, with implementation details including code generation, correlation processing, and threshold detection algorithms.
