地面数字HDTV的规划参数

Planning Parameters of Terrestrial Digital HDTV

本文根据调研和理论计算结果，结合我国实际，提出了供我国地面数字ＨＤＴＶ频谱容纳和规划试算用的规划参数，其中包括射频信噪比、最低场强和射频保护率，以及有关的接收机和接收天线参数，时间概率和地点概率等；并对地面数字ＨＤＴＶ的覆盖范围和同频道间隔距离进行了估算。

This paper according to the research and theoretical calculation results, andcombining Chinese reality,proposes the planning parameters which could be used for frequencyspectrum capacity and planning trial calculation of Chinese terrestrial digital HDTV, includingCNR, E_(min) and PTR, as well as related receiver and antenna parameters, time and locationprobabilities, and also gives a trial calculation for coverage range and co-channel interval ofterrestrial digital HDTV.
