| 摘 要： | 软件无线电接收机要求解调模式灵活可变,并可通过设置参数来改变解调模式。根据自然基金项目要求,从多种经典调制方式中一种重要调制方式：最小频移键控（MSK）的基本模型入手,介绍了一种利用Simulink软件实现MSK仿真的方法,并根据最佳状态接收机的原理设计了一种最佳状态接收机模块,通过改变系统的参数,对结果进行了分析,验证了MSK调制解调的性能。

| Abstract: | The software radio receiver requires flexible and variable demodulation mode,and demodulation mode could be changed by parameter set-up.According to the requirement of Nature Fund project,and from the basic model of MSK signals and the basic theory of modulation,a method that realizes the simulation of MSK digital modulation with Simulink software is proposed.And based on the theory of basic state receiver,a module for achieving the best state receiver is designed.The result is analyzed by changing the parameters of this system,and the functionality of MSK is verified. |
