摘　　要：通过对MSK信号和线性Alamouti系统进行分析,对MSK信号表达式进行了分析推导,使该信号适合线性Alamouti通信系统,使连续相位信号不能直接适用Alamouti通信系统的问题得到解决,这种双天线系统适合小型化用户终端,对这种系统进行了仿真,仿真结果显示在高斯衰减信道下传输时,信号的误码率提高了大约8分贝。The analysis to MSK is finished and formula is deduced in order to adapt MSK signal to Alamouti space-time block codes communication system, which resolve the problem that the continuous phase signal does not directly apply to Alamouti system. The double antennae terminal can apply to mini-communication system. The simulation is fulfilled and re-sult shows that bit error rate is improved 8 db in fading channels.
