基于MIMO系统的快速天线选择算法改进

内容简介：基于MIMO系统的天线选择技术是对收发两端的多根天线根据算法不同，进行不同方式的天线选择，以此降低射频电路成本与复杂度。研究一种更低复杂度的快速接收天线选择算法的改进，它具有较好的系统性能。仿真结果表明，所研究的次优算法，对比于最优算法具有较低复杂度，并且它大大降低了系统硬件链路成本，而系统容量损失极小，并保留系统的优越性。

Abstract：Antenna selection in the MIMO system is some different Antenna selections for multiple transmitting and/ or receiving antennas, and is a low -cost low -complexity alternative. Studies a fast incremental and decremental algorithm for receive antenna selection, with less complexity and good system performance. Simulation results indicate that, in comparison to the optimal algorithm, the suboptimal algorithm with less hardware link complexity can reduce great computation, but with a little loss of system capacity, and remain the system' s superiority.
