摘要
天线选择是MIMO系统中一项重要的技术,它能从MIMO系统的多个发射天线和多个接收天线中选择出性能最好的一个或几个天线,从而以很小的性能损失换取成本的大幅降低,极大地提高了MI-MO系统的性能价格比。最优算法具有较高的复杂度而限制了它的应用,文中从次优的递增递减算法入手,提出了一种具有更低复杂度的递增递减接收天线选择算法。仿真结果表明,该算法以很小的系统容量损失为代价换取了复杂度的降低。
Antenna selection is an important technique in MIMO system, which can select one or several best antennas from multiple transmit and receive antennas, and can reduce the expense with less performance loss and increase the performance-cost-ratio of MIMO system. The optimum algorithm restricts its use because it has a great high complexity. This paper proceeds with the hypo-algorithm（viz incremental and decremental algorithm） and proposes a fast incremental and decremental algorithm for receive antenna selection with less complexity. Simulation results indicate that the algorithm can reduce great computation with a little loss of system capacity.
