| 摘 要： | 针对传统天线选择算法在以误码率作为性能指标进行天线选择时，需要对所有可能的天线子集进行全搜索的缺点，提出了基于修正Gram-Schmidt的QR分解的天线选择算法，并对算法的计算复杂度进行了分析．与以往算法相比。该算法可用于相关信道的场合。并且复杂度明显降低。仿真结果证明了其算法的有效性。

| Abstract: | A novel antenna selection algorithm based on modified Gram- Schmidt QR decomposition is proposed to avoid the shortcoming of conventional methods which need a mass of search over all possible subsets. The complexity of the algorithm is given. Compared with previous algorithms, it works well even under correlated channel and the computation complexity is reduced dramatically. The simulation verifies the effectiveness of the algorithm. |
