摘　　要：在MIMO系统中有选择地使用多根天线,可以大幅增加系统容量,解决无线通信现在面临的资源紧张问题。低秩相关信道进行发送天线选择比不进行天线选择情况可以大大增加系统容量并降低成本。在进行发送天线选择的基础上再进行接收天线选择会使容量比只进行发送天线选择小,但相对于只进行发送天线选择,可使设备复杂度大大降低,对系统的实现具有重要的实用价值。本文首先进行发送天线选择,然后在此基础上进行接收天线选择并进行数值仿真。Multiantenna selection can solve the problem of resource shortage that the wireless communication faces now.Since it can help the system to increase the capacity sharply,using antenna selection in a low rank channel system can increase the capacity and reduce the cost.Athough receive antenna selection after the transmit antenna selection may reduce the system capacity,it can reduce the complexity of the equipments.So it contributes a lot to the practical system.The paper carries on the transmit antenna selection,and then the receive antenna selection.It also shows the corresponding simulation results.
