Simulation of Frequency-Hopping Spread Spectrum Communication System

This MATLAB-based simulation program models the operational principles and performance characteristics of frequency-hopping spread spectrum (FHSS) communication systems. The implementation includes core components such as frequency synthesizers, pseudo-random sequence generators for hop pattern control, and modulation/demodulation modules. Through this simulation platform, researchers can investigate and analyze transmission effectiveness under various conditions including signal-to-noise ratios, interference scenarios, and different hopping patterns. The program's modular architecture allows for parameter adjustments and performance optimization through MATLAB's signal processing toolbox functions, enabling improvements in transmission quality and system reliability. Key algorithmic features include frequency hopping sequence generation using linear feedback shift registers (LFSRs), coherent/non-coherent detection methods, and bit error rate (BER) calculation modules. Overall, this simulation serves as a valuable tool for understanding and applying FHSS technology, with practical code implementation demonstrating real-world communication system behavior.
