摘　　要：天线选择是降低多天线通信系统的硬件复杂度以及改善空域相关性能的有效途径,但对于天线安装空间受限的小型终端,天线的数目将受到很大限制,从而制约了天线选择算法的实施.本文提出一种基于极化可重构天线的天线选择方案,该方案具有紧凑的天线结构和低复杂度的选择算法,适合于小型移动终端使用;通过理论以及数值仿真实验,证明了该方案能明显提高系统性能.Antenna subset selection is an effective method to reduce the number of radio frequency chains and improve the spatial correlation properties.However,the space for the installation of the antenna array is usually limited in practical applications, thus the performance of antenna selection will be limited. Based on the polarization reconfigurable antenna, a low complexity selec- tion scheme is proposed. This proposed scheme possesses compact structure, and can be implemented in small terminals. Significant performance improvement can be shown through theory analysis and Monte Carlo simulations.
