A New Frequency Hopping System and Its Performace of Anti-jamming

Hopping Frequency communication system is one important method of spread spectrum communication, it is widely used in civil and military field. Traditional frequency hopping system has low hopping speed and low data transmission speed, it also has weak anti-jamming performance of tracing. To solve this problem, differential FH system (CHESS) came out, because of its high hopping speed, it is good at anti-jamming performance of tracing. However, it is weak at anti-single-tone jamming. Based on these problems of FH and DFH, A new FH system is designed in a patent paper. In the paper, a new FH system is described. Analysis and simulation in our paper show that the new FH system is more effective in anti-following and anti-single-tone jamming compared with traditional FH system and CHESS.
