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。
Software radio receivers require that the demodulation mode be flexible and variable, and that the demodulation mode be changed by setting parameters. According to the requirements of the Nature Fund project, this paper introduces a basic model of MSK, one of the most important modulation methods of many classical modulation schemes, and introduces a method of simulating MSK using Simulink software. According to the best state Receiver principle designed a best state receiver module, by changing the system parameters, the results were analyzed to verify the performance of MSK modulation and demodulation.
