Research Of Digital Television Terrestrial Broadcasting And Performance Of Channel Concatenated Coding

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 countryAfter 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 workThis 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...
