| Abstract: | The frequency-hopping code-division multiple-access(FH-CDMA)system have recently received wide attention,owing to its anti-jamming and low probability of interception and low detection capability,and the advantage of resistant frequency-select fading and near-far resistant.We have analyzed the frequency efficiency of FHMA in Rayleigh-fading environment.The results show that FFH-CDMA have frequency-diversity potential and can implement frequency-diversity receive and increase the frequency efficiency of cellular FHMA communication systems. |
