Performance of an Orthogonal Multicarrier CDMA System in a Multicell/Multipath Environment

Wonsik Yoon

Abstract

We have considered an improved orthogonal multicarrier (MC) CDMA system. This system combines the advantages of both DS-CDMA with a concatenated spreading scheme and an MC modulation technique to combat the effects of a multipath fading channel and intersymbol interference (ISI). The performance of the system is analyzed under a multicell, multiuser, and multi path Rician fading channel. The system is shown to outperform the orthogonal MC-CDMA system with a conventional PN sequence.
