| Abstract: | The digital HDTV is the new generation of television system which is under researches all over the world . One of the key techniques and major problems in the developing of digital HDTV is that coded orthogonal frequency division multiplexing ( COFDM ) transmission scheme. This paper proposed a COFDM scheme and its hardware implementation . The results of computer simulation are also discussed . |
