In this thesis, the design, the performance of anti-jamming and applications of variable rate frequency-hopping communication module are investigated with the background of wireless environment with the assistant software of MATLAB-Simulink toolbox. The design and simulation of frequency-hopping communication system,tracking-jamming system includes waveform level and spectrum level simulation models of main entities such as fast frequency hopping communication, tracking-jamming system for frequency hopping communications, etc. The most important of all.the design of variable rate frequency hopping module make it easy to achieve establishing variable rate frequency hopping communication by embedding the module into frequency-hopping communication system.Then,analysis the performance of anti-jamming by comparing the simulation results of variable rate frequency-hopping communicationThe purpose of design and experiment is proposing a effective strategy.The function of the simulation system can be extended to offer an effective approach for analyzing and evaluating the efficiency of wireless countermeasure system.First, this thesis describes the basic theory of frequency-hopping communication, and highlights the core components of the frequency-hopping communications: frequency-hopping generator and frequency-hopping sequence generator; then use the Simulink simulation platform to establish the frequency-hopping communication models, jamming models and variable rate frequency-hopping models, analysis each transmission signal’s waveform, spectrum,the bit error rate as well as embed the variable rate frequency-hopping model into the frequency-hopping communication model; the last analysis and compare the performance of anti-jamming of tacking of variable rate frequency-hopping with that of frequency-hopping communication systems, make sure that the variable rate frequency-hopping communication system’s high performance of anti-jamming of tracking,so we draw the conclusion that variable rate frequency-hopping communication is a valid approach of anti-jamming of tarcking.
