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,在现有的天线选择算法中,基于系统容量和基于误码性能的算法具有各自的特点和适用环境。该文在详细分析这两类算法的基础上,提出了一种同时基于容量和误码率的天线选择算法,即SCE算法,并通过仿真详细分析了算法性能。 Antenna selection is an effective method to reduce the number of radio frequency chains and improve the spatial correlation properties. Among the existing algorithms, the ones based on the systemic capacity and error rate have their characters and applicable circumstances respectively. After an elaborate analysis of the two algorithms, a new antenna selection algorithm, i.e. SCE (Simultaneous Capacity and Error-rate) is proposed, and its algorithmic performance is analyzed at length through simulation.
