Synchronous Multi-user Performance Analysis of Differential Frequency Hopping System Over Rayleigh-fading Channels
A type of frequency-hopping system in HF (High Frequency) bands, Differential Frequency Hopping (DFH) system, is presented in this paper. The frequency transition function (FTF) and the methods of signal detection are the key issues for DFH system. Symbol-by-symbol detection and sequence detection are adopted in DFH system. With these two detection methods, the synchronous multi-user performances of DFH system are analyzed over Rayleigh-fading channels. Simulations validate the analyses. The results of analyses and simulations prove that the DFH system with sequence detection can achieve better synchronous multi-user performance than that of conventional frequency-hopping (FH) system.
