| Abstract: | 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. |
