摘要：
In this paper we investigate CDM-OFDMA and MC-CDMA systems comparatively. The impacts of frequency offsets on both systems are studied. Conventional CDM-OFDMA, interleaved CDM-OFDTMA, conventional MC-CDMA, interleaved CDM-OFDMA and MC-CDMA with maximum frequency diversity axe considered. Three aspects are taken into account: system structure, parameter estimation and system performance. It is shown that interleaved CDM-OFDMA is possibly more suitable for uplink transmission than MC-CDMA because of its less parameter estimation complexity.
