Cooperative Multiple Trellis Coded Modulation
MILCOM 2006, 2006In this paper, we consider the design of cooperative multiple trellis coded modulation (CMTCM) schemes over Rayleigh fading channels. We design cooperative multiple trellis codes using asymmetric constellations that provide significant gains over non-cooperative coded modulation without sacrificing the data rate and bandwidth consumption.

On punctured trellis-coded modulation
IEEE Transactions on Information Theory, 1996Summary: Punctured convolutional codes result in some savings in the complexity of Viterbi decoders, compared to other codes of the same rate. However, in general use of the punctured structure in the decoder results in a performance loss for trellis codes, due to difficulties in assigning metrics.

Systematic trellis-coded modulation
Proceedings of IEEE Vehicular Technology Conference (VTC), 2002Systematic trellis-coded modulation (STCM) is a novel approach to coded modulation, which enables symbol-by-symbol detection of trellis-coded data. A set of design rules, which guarantees nonzero coding gain, and codes with asymptotic coding gains of 3.0-5.4 dB are presented. STCM is well suited for operation in a dual-mode receiver.

As it is discussed in Chapter 1, power and bandwidth are limited resources in modern communication systems, and the efficient exploitation of these resources invariably involves an increase in complexity. It has become apparent over the past few decades that when there are strict limits on the power and bandwidth resources, the complexity of ...

Trellis-Coded Unitary Space-Time Modulation
IEEE Transactions on Wireless Communications, 2002Space-time coding is well established for high data rate communications in wireless channels with perfect channel state information. On the other hand, the case where channel state information is unknown has received limited attention. Recently, a new signaling scheme called unitary space-time modulation has been proposed for the latter case.
