摘要： 在对多用户MIMO系统上行链路容量以及多用户MIMO最优天线选择算法进行研究的基础上，提出了一种多用户迭代递减的次优发射天线选择算法，即MIEAS算法，并分析了其复杂度。仿真结果表明，该算法应用在MIMO系统上行链路时，在各种不同参数条件下获得的容量增益均十分接近于最优天线选择算法，且运算复杂度大大降低。

Abstract: Based on the multiuser MIMO uplink capacity and optimal antenna selection schemes, a sub-optimal transmitting antenna selection algorithm is proposed, termed Multiuser Iterative Elimination Antenna Selection (MIEAS). Simulation results show that, when apply to the uplink of MIMO systems, MIEAS provides performance that is very close to the optimal algorithm in capacity, with considerably lowered computation complexity.
