Simulation of Direct Sequence Spread Spectrum (DS) Principles

This simulation program provides comprehensive insights into Direct Sequence Spread Spectrum (DS) principles through interactive code implementation. The program visually demonstrates the working mechanism of DS spread spectrum technology, including core algorithmic processes such as PN code generation, signal spreading modulation, and correlation-based despreading operations. Through real-time simulation, users can observe the complete signal transformation pipeline - from original data sequence to spread spectrum waveform and subsequent signal recovery after despreading. The implementation includes adjustable parameters for chip rate, spreading factor, and SNR settings, allowing experimental analysis of system performance under different conditions. Additional analytical tools provide spectral analysis, bit error rate calculations, and waveform comparisons to facilitate deeper investigation. By interacting with this simulation's code structure and algorithmic components, users can solidify their understanding of DS principles and establish a strong foundation for advanced study and practical applications in communication systems.
