This paper is concerned with the problem of designing reduced-complexity Viterbi decoders for the transmission of digital data over intersymbol-interference channels. First, optimal state-grouping for constructing reduced-state trellises is presented and illustrative examples are given for multilevel transmission over partial-response channels of the type 1 ±D″, (1+D)2, (1+D)2(l-D), and (1+D)3(1-D). Then, the quaternary 1 D type partial-response channel is considered in more detail and a difference-metric algorithm employing state-reduction is derived and shown to result in a simple decoding scheme. © 1992 IEEE
