| Abstract: | Symbol-by-symbol detection and sequence detection are adopted in differential frequency-hopping (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) systems. |
