摘　　要：多包接收MPR(Multi-Packet Reception)技术能够极大地提高无线网络吞吐量,它可以同时接收多个数据包并进行有效的分离。多输入多输出系统MIMO(Multiple-Input Multiple-Output)是一种实现MPR的高效技术,对提高无线通信系统性能具有重要意义。文章对4×4天线配置下的MIMO系统MPR进行仿真并分析其误码性能。仿真分析表明,MIMO不仅能获得分集和复用增益,而且能实现一种多包接收功能并能同时正确分离多个数据包。Multi-packet reception （MPR） techniques can greatly improve the throughput of the wireless networks in high traffic conditions. MPR can separate many packets which the node receives simultaneously. And MPR can be realized by multiple-input multiple-output （MIMO）. In this paper, simulations are displayed to analysis the performance of MIMO MPR system with 4x4 antennas. The results show that MIMO not only obtain spatial multiplexing and diversity gain but also act as MPR technique.
