Abstract
A Viterbi decoder for receiving and decoding a signal transmitted through a transmission channel in a vestigial side band (VSB) transmission system, in a high definition television (HDTV), which operates at the same speed as a symbol rate, can simply accomplish a hardware implementation using simplified memory system and a single decoder in order to restore an encoded signal, compared to the conventional art in which 12 decoders are used in restoring the encoded signal. Also, since the memory configuration thereof is regular, when it is intended to extend the observation sections, the memory structure can be extended easily. Moreover, the present invention can be adopted by extending easily to 3-bit 8 state or above as well as to 2-bit 4-state by means of a general Viterbi decoding algorithm.
