Abstract :
Digital transmission and recording technologies such as direct broadcasting by satellite and DVD are revolutionizing the home-entertainment consumer electronics industry. It would be economical and convenient to use a single “set-top box” receiver for multiple services. Based on an analysis of the standards for digital audio broadcasting (DAB), digital video broadcasting (DVB) and DVD, a Viterbi decoder and a Reed-Solomon decoder are found to be common channel decoding components that would benefit from co-integration. This paper presents the synthesis-based design and test results of a 62.5 Mbps output rate multi-standard Viterbi decoder implemented in a 0.35 μm CMOS process
