摘要 提出在LTE上行采用2×2模式的虚拟MIMO(Virtual MIMO,V-MIMO)系统,即一个两天线的基站同时支持两个单天线的用户,并在此基础上,提出一种基于传输延时的干扰对准算法.这种算法将基站的双天线的接收信号按照奇、偶时隙分离,从而将期望信号与干扰信号分离.应用本文算法一个两天线的基站可以支持3个甚至4个用户同时接入LTE网络的上行链路. We proposed a virtual MIMO （V-MIMO） system using the 2 × 2 pattern for LTE uplink, i. e. × a two antennas＇ base station supports two single antenna＇s users simultaneously. With the V-MI- MO, the paper designed one kind of interference alignment algorithm for LTE MIMO based on the transmission time delay. The algorithm separates base station＇ s receiving signal by odd time slot and even time slot, thus expected signal and unexpected signal are separated for UEs. A two antennas＇ base station may support 3 even 4 users simultaneously by using our algorithm to access the uplink of LTE network.
