MATLAB-based Frequency Hopping Communication - Implementing a Fast Frequency Hopping Communication System with MATLAB, including sequence generation, modulation/demodulation algorithms, and performance analysis
This project implements a fast frequency hopping communication system simulation using MATLAB, primarily utilizing SIMULINK and Communication Blockset modules. The design incorporates six key components: signal source generation, transmission unit, frequency hopping modulation, channel simulation, reception module, and result analysis. Core technical elements include pseudo-random sequence generation and frequency synthesizer design, with synchronization of pseudo-random codes between transceivers being the critical implementation challenge. Pseudo-random codes are generated through S-function programming to create custom SIMULINK blocks, while synchronization is achieved using identical spreading pulse triggers at both transmission and reception ends. Each module employs encapsulation techniques to simplify block diagram structures.
