本课程设计主要运用MATLAB集成环境下的Simulink仿真平台设计一个AM调制与非相干解调系统，并把运行仿真结果输入到显示器，根据显示结果分析所设计的系统性能。在课程设计中，首先根据原理构建调制解调电路，再在Simulink中调出各元件组成电路，再设置调制解调电路中各个模块的参数值并加以运行，并把运行仿真结果输入显示器，根据显示结果分析所设置的系统性能。-This course is designed primarily integrated environment using MATLAB Simulink simulation platform design an AM modulation with non-coherent demodulation system, and to run the simulation result is input to the monitor, display the results analyzed according to the design of system performance. In the course design, the first modem circuit constructed according to the principle, and then tune in Simulink components of each circuit, and then set the modulation and demodulation circuit parameter values ​ ​ of each module and to run, and to run the simulation result input displays, according to Showing results analyzed set system performance.
