Abstract: Based on the introduction of frequency-hopping communication system and its mathematic model, a simulation model was built using Matlab/Simulink. In the simulation model, the core components of frequency-hopping system, including frequency-hopping sequence generator, frequency synthesizer, frequency hopping synchronizer and nonconherent FSK demodulator were designed and implemented. Simulation test was done with satisfied result. The performance of frequency-hopping system in various conditions could be analyzed and evaluated through the bit error rate curve of the proposed model, such as anti interferce, anti multi-path fading and multiple access networking.
