摘要
本文提出一种数字ＨＤＴＶ信号的ＭＱＡＭ系统经衰落信道传输的数学模型。利用所提出的模型，分析和讨论了衰落信道对该传输系统相位特性和误码性能的影响。
This paper proposes a mathematical model which is used to describe MQAM systemof digital HDTV signals propagated by fading channels.The influence of fading channelson phase characteristic and BER performance of the system are analyzed and discussedusing the given model.
