毕业论文MSK调制解调系统的设计说明

MSK 调制解调系统的设计XX（XXXX 学院 物理与电信学院 XXX 级 X 班 XX XX AAAAA）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纳。本文讨论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与 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与其分析讨论结果。[关键字]MSK； Matlab；Simulink；调制解调Simulation of MSK Modulation and Demodulation SystemXX XX(XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX)Tutor: XXi[Abstract]Minimum Shift Keying (MSK) isaconstant envelope modulationtechniques,ithasacontinuous phase, highbandwidth efficiencycharacteristics,isvery attractiveinthefieldofwireless communications,digitalmodulation, shortwave,microwave andsatellite communicationsmedium wereused.In this paper,theworking principleofminimum shift keyingmodulation anddemodulation, and givesthe realizationofprogramsimulation andsimulinksystemmoduleintheMATLAB softwareenvironmenttobuildin two ways.
