   Abstract:
   A new technique is proposed for constructing trellis codes, which provides an alternative to Ungerboeck's method of “set partitioning.” The new codes use a signal constellation consisting of points from an n-dimensional lattice A, with an equal number of points from each coset of a sublattice A'. One part of the input stream drives a generalized convolutional code whose outputs are cosets of A’, while the other part selects points from these cosets. Several of the new codes are better than those previously known. © 1987 IEEE
