Abstract
The multilevel coding approach of Imai and Hirakawa (1977) is used to construct trellis-matched codes for binary-input partial-response channels. For the codes to be trellis matched, the signal constellations are selected according to certain constraints, but no conditions are imposed on the component codes. New codes for the (1-D)(1+D)/sup n/ channel compare favorably to existing codes.
