ABSTRACT:
An M-dimension M-PAM trellis code encoder, a method of encoding user bits and a decoder. In one embodiment, the encoder includes: (1) a convolutional encoder portion configured to encode at least two user bits into at least three coded bits and (2) a sublattice selector coupled to the convolutional encoder portion and configured to employ the at least three coded bits to select a particular sublattice of code alphabet elements and further to employ at least two additional user bits to select a particular code alphabet element in the sublattice.
