摘要 本文首先介绍了一种实用的发射分集技术——循环延迟分集(CDD),以及其在编码的OFDM(COFDM)系统中的应用;接着给出其系统模型;然后分析该技术在COFDM系统中的性能、参数设置,以及和空时分组码相比较的技术优势;最后介绍了该技术在EBCM CS和M C-CDMA中的应用。 This paper introduces a practical transmit divers diversity firstly, and its applications in coded-OFDM systems. forward then. Its performance and parameter optimization in COF compared to STBCs is analysed later. Finally, the applications of ity technique-cyclic delay Its system model is put DM system and advantages this technique in EBCMCS and MC-CDMA are presented.
