1、陕西理工学院毕业设计MSK调制解调系统的设计XX（XXXX学院物理及电信学院XXX级X班XXXXAAAAA）指导老师：XX[摘要]最小频移键控（MSK）是恒定包络调制技术，它具有相位连续、频带利用率高的特点，是在无线通信领域中很有吸引力的数字调制方式，目前在短波、微波和卫星通信中均被采用。本文研究了最小频移键控系统调制与解调的工作原理，并给出了基于MATLAB软件环境下的程序仿真及simulink下系统的模块搭建实现两种方式的实现。运用m语言进行仿真，主要是依照MSK系统的工作原理绘制出流程图，最后写出程序进行仿真，并给出每一步骤的仿真结果

2、图形。运用simulink进行系统的模块搭建，是将系统分为调制与解调两个子模块，再将这两个子模块连接成整体的MSK系统模块进行仿真。最后给出全系统的仿真运行结果及其分析研究结果。[关键字]MSK；Matlab；Simulink；调制解调陕西理工学院毕业设计SimulationofMSKModulationandDemodulationSystemXXXX(XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX)Tutor:XXi[Abstract]MinimumShiftKeying(MSK)isa
