| 摘 要： | MIMO系统是无线通信领域的研究热点,他能够极大地提高通信系统的容量和频谱利用率。然而使用多个射频的MIMO系统增加了天线的体积、功率和硬件,从而增加了成本。因此寻找具有MIMO天线优点且低价格、低复杂度的最优天线选择极具吸引力。总结了天线选择的方案、介绍了两类关键实现算法和最新研究进展,并在性能上进行分析比较,最后指出了该技术的实际应用问题。

| Abstract: | Multipleinput Multipleout(MIMO) system has became hot spot in wireless communications,which can improve the capacity and reliability.However,the multiple RF chains associated with it are costly in terms of size,power and hardware.Optimum antenna selection is an efficient way to decrease cost and complexity while it captures many of the advantages of MIMO systems.The paper summarizes the schemes of antenna selection.In the following,the implementation and performances concerning two categories algorithms of antenna selection are analyzed and compared with each other.At last we present an overview of the application problems of antenna selection in MIMO system. |
