本文介绍了QAM调制、解调和判决原理，讨论了QAM的误码率性能，并在SystemView下对QAM调制、解调系统进行了仿真，观察并分析了原始输入信号、调制信号、解调信号、星座图以及QAM信号的功率谱图。-QAM modulation, demodulation and sentencing principle, the QAM BER performance, and right under the SystemView QAM modulation, demodulation system f

下面是我编的用matlabe语言编的64QAM调制解调的程序 可是解调后，不能恢复64点的星座图了，-Below is Part I of the language used matlabe series 64QAM modulation and demodulation process demodulation However, unable to return 64 points of the constellation,

基于MFC的调制信号发生器的波形和星座图设计-Constellation design based on the waveform and the modulation signal generator MFC

采用MATLAB实现16QAM的调制与解调，并画出星座图。-Using MATLAB 16QAM modulation and demodulation, and draw the constellation.
