摘要

对空分复用技术中的非理想因素进行了理论分析，并探讨了在上述非理想工程条件下空分复用的应用，给出了实测数据。对于信道条件非理想的场景，即多通道之间相关性高，条件数大，导致高层间干扰，需要通过最优化用户匹配和降维达到最优容量。对于信道测量非理想的场景，深入分析了反馈式和非反馈式的优劣，并指出即使信道不满足互易性条件，非反馈式也是优选方法。针对上述问题，进行了理论分析和外场实测。

Abstract

We study the performance of space division multiple access (SDMA) under a non-ideal engineering situation. When the SDMA channel is of high inter-layer correlation and the condition number is large

the multiple user multiple input and multiple output user equipment (MUMIMOUE) grouping should be optimized

and in some cases further dimension-reduction should be applied. As the channel measuring is always non-ideal

we use two methods

feedback mode and non-feedback mode

in terms of performance and overhead. It is proposed that the non-feedback mode is preferable even for some non-reciprocal channels. Principle analysis and test results are given.
