【摘要】 针对空间相关性中存在严重制约MIMO系统性能的问题,提出了一种具有鲁棒性的空间相关MIMO系统的接收方案。在发送端采用Alamouti编码以提高发射分集,接收端则将信道传输矩阵进行重建后,利用V-BLAST分层排序干扰抵消算法进行检测。仿真结果表明该方案在保证系统吞吐量和频谱利用率的同时,较之传统V-BLAST接收方案,具有更强的抗空间相关性能力,且复杂度较低。更多还原

【Abstract】 The existence of spatial correlation will severely degrade the performance of MIMO systems, we propose an algorithm called Space Time Robust to Correlated MIMO (STRCM) that Alamouti’s code is utilized to obtain the transmit diversity, V-BLAST order interference cancellation detection is adopted in the receiver directly via the grouping and reconstruction of channel matrix. Simulations show that the proposed scheme is more robust to spatial correlation than V-BLAST, and the complexity is not increase.更多还原
