Simulation of Bit Error Rate with Different Spreading Gains and Sinusoidal Interference

This simulation conducts detailed analysis of bit error rate (BER) performance under varying spreading gains and sinusoidal interference scenarios to understand their correlation relationships. During the simulation process, the BER variation can be observed by incrementally increasing the spreading gain parameter, while sinusoidal interference signals are introduced to emulate real-world jamming environments. These simulation experiments enable comprehensive understanding of how spreading gain and sinusoidal interference impact BER performance, providing valuable references for further research and system optimization.

Implementation approach typically involves generating spread spectrum signals using pseudo-random sequences (e.g., Gold codes or m-sequences) with configurable spreading factors. The sinusoidal interference can be modeled as a narrowband signal with adjustable frequency and amplitude parameters. Key functions would include signal modulation/demodulation modules, BER calculation algorithms using Monte Carlo simulations, and comparative analysis of signal-to-interference ratios under different parameter configurations.
