摘　　要：分析了采用Alamouti编码方案(ACS)的两发射天线和多接收天线系统(2Tx-mRx)的工作原理,描述了Alamouti码的编码、解码规则,从理论上对最大似然(ML)判决估计器给出了易于理解和实现的仿真算法。证明了采用ACS的2Tx-mRx系统的分集增益.理论分析和仿真结果表明:常用的2发4收或4发2收均具有相同的较高的增益。The Theary of Alamouti Coding Scheme （ACS） with two transmitting antennas and multiple receive antenna system （2Tx -mRx） is analyzed. The Alamouti encoding and decoding rules are described. The simulation algorithm that it is easy to understand and realize is given to maximum likelihood （ML） estimator decision in theory. The ACS system 2Tx - mRx diversity gain is proved. Theoretical analysis and simulation results show that the mode using 2Tx and 4Rx or 4Tx and 2Rx have the same high gain.
