Performance Comparison of FWMC DS-CDMA with Single- and Multi-carrier DS-CDMA'

Abstract: In this contribution we review the slow frequency hopping multicarrier direct-sc~qlit~rtcc code-division multiple-access (SFH/MC DS-CDMA). Then, the system's performance is t~\~ullrtrrt~~l and compared to that of the conventional single-carrier (SC) DS-CDMA and MC DS-('I).\l..l. under the assumptions of constant system bandwidth and of constant transmitted sigr~ul p t r \ r cvr Both random and 'uni$ormlFH are considered and their advantages as well as disadvanrugt~+ urc. investigated. We assume that the system operates in a multipath Nakagami-m fading en\.ironnrt.nr and a maximum ratio combining (URC) assisted RAKE receiver is used for demodulatiot~
