An Efficiency Analysis of Differential Frequency Hopping Communication Anti-jamming

Differential frequency hopping communication system is a sort of new concept commu-nication system based on comprehensive digital signal processing,and it differs completely from conventional frequency hopping in technology system and principle.The differential frequency hopping has become an important development direction in the current shortwave privacy communication,so its anti-jamming performance is particularly a concern.In virtue of the special communication mechanism of the differential frequency hopping system,its anti-jamming efficiency is completely different with the conventional frequency hopping communication system.In view of this,based on the research of the differential frequency hopping communication theory,the efficiency of differential frequency hopping communication system anti-jamming to the same frequency jamming and different frequency jamming is especially analyzed,and the corresponding conclusions have been verified by computer simulation.It can afford interrelated theoretical basis and technical reference for the further development of the differential frequency hopping communication.
