Effect of carrier separation with bandwidth limitation on theperformance of multi-carrier DS-CDMA systems in multipath fadingchannels

摘要

We study the downlink performance of the multicarrier CDMA systemin a multipath fading channel. The number of carriers and theintercarrier frequency separation are variables, which makes theorthogonal multicarrier and/or orthogonal multicodes as well as theconventional CDMA systems special cases. We show that a considerableperformance improvement can be achieved with a multicarrier system
