摘要
基于正交频分复用 (OFDM)与CDMA技术相结合的OFDM CDMA在未来宽带无线通信中将占据非常重要的地位。文中在介绍OFDM CDMA基本原理的基础上 ,给出OFDM CDMA的基本结构框图 ,并由此推导出MC CDMA ,MC DS CDMA ,MT CDMA三种基本的OFDM CDMA方案和其结构图。还对OFDM
The technology of Orthogonal Frequency Division Multiplex(OFDM) combined with Code Division Multiple Access(CDMA) will take an important role in the future wideband wireless communications.Based on the introduction to the basic theory of OFDM-CDMA,the basic architectural scheme of OFDM-CDMA is given.Then the architectural scheme of the OFDM-CDMA Communication Systems including MC-CDMA,MC-DS-CDMA,MT-CDMA are derived.At last,the various interferences in an OFDM-CDMA System suffered from multi-carrier transmission are briefly analysed.
