提出一种基于波束赋形(BF)的空分复用多输入多输出(MIMO)接收方案，该方案兼具MIMO多流接收和 BF抗干扰的优点。针对平坦衰落信道，建立了基于空间相关的 BF-MIMO接收系统模型，推导出了系统接收误码率表达式，阐明了角度扩展与系统抗干扰性之间的关系。理论分析和仿真结果表明，该接收方案在小角度扩展条件下较普通 MIMO 系统具有更优的抗干扰和误码率性能。

A spatial multiplexing Multiple Input Multiple Output(MIMO) receiving scheme based on beamforming is proposed. Combining MIMO and Beam Forming(BF),the proposed scheme takes the advantages of both multi-stream receiving and anti-jamming. Aiming at flat fading channel,a BF-MIMO spatial correlation channel model is set up firstly. Then Bit Error Rate(BER) expression for the system receiving is derived. Finally,the relation between Angle Spread(AS) and system anti-jamming performance is investigated. Theoretical analysis and simulation results show that the proposed scheme could provide better anti-jamming and BER performance than traditional MIMO techniques under small AS environment.
