Analysis and Design of Jamming System for Frequency Hopped Communications Using BFSK Based on Simulink

In this thesis, the design, the performance and applications of jamming systems for frequency-hopped communication countermeasure based on Armored Vehicles are investigated with the background of link simulation system for communication countermeasure system in field operations and with the assistant software of MATLAB-Simulink toolbox. The design and simulation of jamming system includes waveform level and spectrum level simulation models of main entities such as a fast frequency-hopped binary frequency-shift keying (FFH/BFSK) spread-spectrum (SS) communication system and the jamming of fast frequency-hopped BFSK SS communication system, etc. The simulation can analyze the performance of the jamming methods; it can give us a new choice to make the jamming systems more useful for frequency-hopped communication which is suitable for the complex electromagnetic battlefield environment.
