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 is an efficient digital modulation method that is widely used in various communication systems. First of all, the principle of 64-QAM modulation / demodulation is studied theoretically. Then, with Optisystem optical simulation software, a 64-QAM transmission / reception model is built and the receiving and transmitting modules of the model are analyzed in detail. Finally, The transmission performance has been verified by simulation. The simulation results show that the constellation of receiver 64-QAM is clear, that is, the 64-QAM modulation format can effectively realize the data signal transmission. This model can provide theoretical guidance for practical engineering design.
