Abstract(in English) | An Ultra-high-speed(higher than 60MHz)Viterbi decoder VLSIC with coding rates from onehalf to fifteen-sixteenth and a constraint length of seven for forward error correction(FEC)has been developed using 0.8-mm semi-custom CMOS LSIC technology.To reduce the power consumption of the one-chip high-coding-rate Viterbi decoder,a newly developed universal-coding-rate scarce- statetransition(SST)Viterbi decoding scheme and low-power- consumption burst-mode-selection(BMS)path memory have been employed.In addition,a new maximum-likelihood-decision(MLD)circuit for the SST Viterbi decoder has been developed to reduce the path memory length without any coding-gain degradation.The developed Viterbi decoder VLSIC achieves a maximum operation speed of 60MHz and achieves near theoretical net coding-gain performance for various coding rates. |
