碩士 === 逢甲大學 === 電子工程所 === 94 === With the advances of science and technology, television broadcasting also moves into the digital era. Therefore, channel coding-decoding is worthy of conferring and researching because it is important for digital television broadcasting systems. The DVB-T published by European Broadcast Union makes use of Reed-Solomon code and viterbi decoder for channel codec. In this thesis we, first at all, compare some Reed-Solomon decoders that take account of area and find the best algorithm of them in this system. Thereafter we reform a structure of finite field multiplier which reducing the amount of logic gate without losing operation speed to optimize the speed of a Reed-Solomon decoder after reducing area. By the two ways, this decoder is designed with VHDL and verified through APEX20K Demo Board by Logic Analyzer. It occupies 2228 logic elements and 5400 memory bits.
