M. Hara et al., A high speed viterbi decoder using path limited PRML method and its application to 1/2 inch HD full bit rate digital VCR, IEEE CONS E, 47(1), 2001, pp. 80-86
A new algorithm called Path Limited PRML is described, which has been used
to implement a high-speed Viterbi decoder LSI. This LSI has been used to re
alize an experimental 1/2" DVCR at 1.3Gbps.
