| Abstract: | This paper mainly describes the error correcting system adopted by the digital television sound of Japanese BS-2 Broadcasting Satellite which consists of BCH error-correcting code in conjunction with the interleaving code, and provides the error correction coding and decoding circuit developed by ourselves. Based upon the conventional BCH coding and decoding circuit, the table examining decoding method with the advantage of simple circuit and less decoding time is proposed, and its applicable range is also discussed. |
