Abstract :
A new transmission scheme, frequency hopping multicarrier code division multiple access (FH-MC-CDMA), is proposed and investigated. This scheme can be compatible with existing narrowband second-generation frequency hopping and third-generation wideband CDMA systems. Two receiver combining techniques, namely equal-gain-combining and maximum-ratio-combining, are considered. An analysis of the downlink bit error rate in slow frequency-selective Rayleigh fading is provided. Two frequency-hopping (FH) schemes, namely random and coordinated FH are used. The performance improvement of the FH-MC-CDMA system over conventional frequency hopping is demonstrated, with a capacity gain approaching that of MC-CDMA but using a much lower number of subcarriers.
