As the step of the color tv ( the second generation ) to the digital tv ( the third generation ) is larger and larger , the research of digital television terrestrial broadcasting ( dttb ) become more and more important in china , we are concentrating on the standard of dttb which is suit for our country after describing and analyzing the technical stipulation and speciality of dttb , this paper compares atsc 8 - vsb with dvb - t cofdm and isdb - t bst - ofdmo the emphasis of this article lies in the technical solution about transferring system , channel coding is important component of dttb , which can resist from the bad circumstances o because of lots of varieties and different performance , channel coding become one of the emphasis of the research work this paper analyzes and researches the theory and performance of the different channel coding particularly , points out an effective theoretic analysis method and computer demo of performance comparison a theoretical method for estimating the performance of concatenated codes is proposed in this paperc this is achieved by combining the performance of single level coding rayleigh fading channel and the character of channel modulation it may be useful to research and development of the future digital television terrestrial broadcasting standard of our country 信道糾錯編碼是數字電視地面廣播傳輸系統的重要組成部分,是抵御地面惡劣環境的有效手段。由于信道編碼的種類繁多,性能各異,因此是目前研究工作的重點之一。本文詳細分析和研究了幾種信道糾錯編碼的原理和性能,并針對外碼內碼級聯糾錯結合地面信道瑞利衰落提出了一種有效的理論分析方法和性能的計算機比較演示方案,總結了不同級聯方案的性能特點,對于我國目前的數字電視地面廣播標準的研究和信道級聯糾錯方案的確立及其參數選擇具有一定的參考價值。
