说明：  随着信息容量的增加和频率资源的稀缺，为提高单位频带利用率，在微波通信系统中越来越多地采用多电平多相位的复杂信号调制方式，尤其是正交幅度调制(QAM)得到了大量的应用，从早期的4QAM到今天的16QAM。高阶QAM调制大容量数字微波通信系统为了保证服务质量，降低误码率，(long with the increase of information capacity and frequency resource scarcity, for improving the utilization ratio, unit of microwave communication bandwidth used more and more in the system of multilevel much phase modulation method complex signal amplitude modulation )
