直扩MSK解调方法分析与仿真

摘要

根据MSK信号的特点，分析了直扩MSK信号的解调方法。基于两种可能的应用形式，在Matlab／Simulink环境下搭建了直扩MSK信号差分相干解调与包络非相干解调的仿真模型。然后进行了性能仿真。所得结论为直扩MSK信号解调的实际应用提供了参考。%According to the characteristics of the MSK signal,the demodulation method of direct sequence spread spectrum MSK was analyzed.The simulation model of DSSS MSK signal difference coherent demodulation and non-coherent demodulation envelope method was established under the Matlab/Simulink condition based on two application modality. Then,the performance simulation was did.The reference was provided to the application of DSSS MSK signal demodulation according to the result of simulation.
