| 摘 要： | 将载波干涉技术与OFDM,MC-CDMA技术相结合的CI-OFDM,CI/MC-CDMA成为宽带无线通信领域新的研究热点之一。在前期研究的基础上，对CI/MC-CDMA的原理进行理论分析，证明了CI/MC-CDMA在原理上与CI-OFDM的相似性#理论分析CI/MC-CDMA系统等效于单载波系统，将载波干涉技术与MC-CDMA技术相结合无法提高MC-CDMA系统性能。

| Abstract: | CI-OFDM and CI/MC-CDMA, which combine carrier interferometry with OFDM and multicarrier CDMA system, have become a new hotspot in the wideband wireless communication. By extending previous analysis of PO/ CI-OFDM, this paper reviews on the theory of CI/MC-CDMA and concludes that CI/MC-CDMA has similarity to CI-OFDM in theory. Theoretical analysis shows that CI/MC-CDMA is equivalent to a single carrier system, and it cannot promote the performance of MC-CDMA system by combining with carrier interferometry technology. |
