Abstract:

This paper presents a new hopping system,which is called the Differential Frequency Hopping(DFH) system.First it introduces the basic theory of the Differential Frequency Hopping(DFH) system,and studies the performance of the Differential Frequency Hopping(DFH) system and DFH networking.The performance in AWGN by using these two methods is analyzed respectively in theory,and the corresponding simulation results are given.Simulation results show that the smaller the number of the system users,a smaller error rate means a smaller interference at the corresponding SN ratio.

Key words: differential frequency hopping;BER;AWGN
