摘要 64-QAM是一种高效的数字调制方式,广泛应用于各种通信系统中。首先对64-QAM的调制/解调原理进行了理论研究,然后借助Optisystem光仿真软件,搭建了64-QAM传输/接收模型,并对模型的接收和发射模块进行了详细的分析,最后对模型的传输性能进行了仿真验证。仿真结果表明,接收端64-QAM的星座图清晰,即64-QAM调制格式能有效地实现数据信号的传输,该模型能为实际的工程设计提供理论上指导。 64-QAM,as a highly efficient digital modulation method,is now widely used in various communication systems.The article first makes a theoretical study on the 64-QAM modulation /demodulation,then with the help of Optisystem simulation software,the simulation model of 64-QAM transmitter / receiver is constructed,and its receiver and transmitter modules are analyzed in detail.Finally,the transmission performance of the model is simulated and verified,and the simulation results indecate that the constellation of 64-QAM in receiver is clear,and the 64-QAM modulation format could effectively implement the transmission of data signals.The model could provide a theoretical guidance for the practical engineering design.
