摘要 通过天线选择可以提高多输入多输出(MIMO)系统的容量,并能有效地降低MIMO系统的复杂度和射频成本。基于连续选择使MIMO系统容量增加最大的天线的方法,用矩阵及行列式运算导出了一种新的接收天线选择算法。将该算法用于分布式MIMO系统的容量研究,通过计算机仿真,结合Rice因子K及不同视距传播条件等因素对分布式MIMO系统上行信道容量的影响进行了研究。仿真结果在分布式无线通信组网及网络优化中具有指导意义。 Antenna selection techniques can not only increase capacity of multiple-input- multiple-output （MIMO） systems, but also reduce their complexity and cost of RF （radio frequency） chains. The pro- posed novel algorithm is established on some matrix and determinants computation. In the novel algorithm, receiving antenna that can offer the best incremental capacity of MIMO system is selected successively. The novel algorithm is used to analyze the capacity of distributed MIMO systems. The uplink channel capacity of the distributed MIMO systems is investigated under the condition of shadowing and different Rice channel factor K and different light of sight, which can benefit the construction of wireless communications and optimization of wireless network.
