| 摘 要： | 本文首先建立了采用TR-STBC发送分集的MIMO MC DS-CDMA系统模型,然后在此基础上,研究了SDCMA盲均衡在该系统中的应用,最后进行了仿真和分析.结论是对采用TR-STBC方案的MIMO MC DS-CDMA系统进行常模盲均衡,算法简单,较易实现,但当多址干扰较大时,仅采用此均衡方法不能较好地改善系统性能,还需要进一步采用其他方法来减小或消除多址干扰.

| Abstract: | This paper first builds up the model of the multiple input multiple output(MIMO) multicarrier direct sequence-code division multiple access(MC DS-CDMA) system with time reversal space-time block coding(TR-STBC) transmit diversity,based on which the application of steepest decreasing constant modulus algorithm(SDCMA) for blind equalization is studied.Finally simulations are performed and the conclusions are given.The conclusions are that blind equalization of constant modulus algorithm(CMA) has low complexit... |
