Abstract
Using a modified Wei method, originally designed for additive white Gaussia n noise (AWGN) channels, we have constructed four-dimensional (4-D) and six -dimensional (6-D) trellis codes with rectangular signal constellations for frequency-nonselective mobile radio channels, Applying a novel way of part itioning the two-dimensional (2-D) constituent constellations, both into su bsets with enlarged minimum Euclidean distance and subrings including equal energy signal points, we have obtained partitions of the 2N-D signal sets into subsets with a Hamming distance between signal points which equals N. This is fundamental for constructing good trellis codes to transmit data ov er flat fading channels.
