This article describes the basic working process of FH systems, and describes the basic principles of frequency hopping communication from the composition of the frequency hopping system, mathematical model, the main technical indicators, Frequency hopping communication system solution to jump and demodulation and other aspects of the basic principle of frequency hopping communication.It focuses on the interference frequency hopping communication system and the performance of the theoretical analysis and simulation. Paper theoretically analyzes the typical communication interference effects on the frequency hopping communication systems, including the signal generation part, sending part , the receiving part , the ruling part and hopping sub-module part, and using Matlab Simulink system implementation in the frequency hopping system simulation and analysis, to achieve the desired effect.
