Abstract :
We study the downlink performance of the multicarrier CDMA system in a multipath fading channel. The number of carriers and the intercarrier frequency separation are variables, which makes the orthogonal multicarrier and/or orthogonal multicodes as well as the conventional CDMA systems special cases. We show that a considerable performance improvement can be achieved with a multicarrier system
