摘要

基于复正交设计的空时编码在发射天线数大于2时不能同时达到满速率全分集，针对这个问题，利用正交空时分组码系统的等效信道矩阵的正交性及系统信道信息的反馈，提出了两种针对闭环扩展正交空时分组码的改进设计方案。系统在接收端以最大等效信道增益为目标进行设计，分别结合天线选择技术和功率自适应分配技术进行信道信息的反馈，并对其性能进行理论分析与比较，仿真结果显示，两种改进方案均能减小系统的误码率，提高系统的信噪比增益，和结合天线选择技术的方案相比，与功率自适应分配相结合的设计方案性能更为优越。

Abstract

For the problem that complex orthogonal design of space-time coding cannot reach full speed and full diversity when the transmitting antenna number is greater than two

two kinds of improved schemes for the closed loop EOSTBC were proposed

which used the orthogonality of the equivalent channel matrix and the feedback of the channel information in the STBC system. The system was designed to maximize the equivalent channel gain. The first scheme was combined with antenna selection techniques and the second was combined with adaptive power allocation. Also

the feedback information was carried respectively. Then its performance was theoretically analyzed and compared. The simulation results show that the bit error rate of the system is reduced and the signal-to-noise ratio gain of the system is improved by the two kinds of improved scheme

and compared with the scheme which is combined with antenna selection technology

the performance of the second scheme combined with adaptive power allocation is superior.
