It has been well established that the appropriate criterion for optimum trellis-coded
modulation design on the additive white Gaussian noise channel is maximization of the free …

BACKGROUND OF THE INVENTION This invention relates to transmission of trellis coded
modulation (T CM) of digital voice and data, and more particularly to TCM in combination …

A suboptimal trellis coding approach based on the concept of combining a good
convolutional code and bit interleavers is presented. The aim is to improve the reliability of …

This work presents an exact expression for the pairwise error event probability of trellis-
coded modulation (TCM) transmitted over Rayleigh-fading channels. It includes phase shift …

A description of the algorithms to evaluate the main parameters determining the
performance of a trellis-coded modulation (TCM) scheme is presented. TCM schemes are …
