HDTV地面廣播信道的建模
THE CHANNEL MODELING FOR TERRESTRIAL BROADCASTING OF HDTV
-
摘要: 本文在參考了各種VHF/UHF信道模型的基礎(chǔ)上,提出了一種專用于HDTV地面廣播的信道模型。該模型充分考慮了HDTV信號在地面廣播途徑中所遇到的三類主要干擾,對HDTV傳輸系統(tǒng)的研究具有十分重要的意義。

Abstract: A channel model specially applied to the terrestrial broadcasting of high definition tele-vision(HDTV) is presented on the base of analyzing some kinds of channel models over VHF/UHF. The model sufficiently concerns main interferences faced by HDTV signal in terrestrial broadcasting path. It is very helpful to researches of HDTV transmission system. -
