摘要
本文介绍了在光纤／同轴混合网（ＨＦＣ）中，用于数字视频信号传输的单片集成正交移幅键控（ＭＱＡＭ）调制／解调器的原理，说明了ＭＱＡＭ调制／解调器状态寄存器参数的设计方法，最后给出了实测结果．
The principles of single chip Multi level Quadrature Amplitude Modulation(MQAM) modem, which is used for the digital video signal transmission in the Hybrid Fiber Coax(HFC) network, are introduced. The design methods of the state register parameters in the MQAM modem are described. The test and measurement results are also given.
