Trellis Coded Generalized Spatial Modulation
2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014In this paper, a novel trellis coded generalized spatial modulation (TCGSM) scheme is presented and analyzed. Similar to that of the traditional generalized spatial modulation (GSM), a subset of the entire transmit antennas is selected for transmission at each time slot.

Trellis coded modulation for informed receivers
2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017We consider the following variant of the index coding problem. A transmitter wishes to communicate several messages, each of which is k bit long, to multiple informed receivers over a noisy broadcast link. Each informed receiver already knows some of the messages a priori, which is called its side information, and demands to know the rest of the ...

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.

Trellis coding for spatial modulation
2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU), 2011In this study, by combining trellis coding with spatial modulation (SM), a new multiple-input multiple output (MIMO) communication scheme called trellis coded spatial modulation (TC-SM) is proposed. For uncorrelated Rayleigh fading channels, code design criteria are given by deriving pairwise error probability (PEP) of this system, in which a trellis ...

On trellis modules for convolutional codes
Proceedings IEEE International Symposium on Information Theory,, 2003We consider trellis modules for convo- lutional codes based on time-varying codes. I. EXTENDED SUMMARY Let C denote a convolutional code over GF(2), with block length n, k information bits and overall memory U (where v is the smallest integer such that C has an encoder requiring only U delay units), and free distance d.

Combination of block-coded modulation and trellis-coded modulation
IEE Proceedings I Communications, Speech and Vision, 1991It is known that trellis-coded modulation (TCM) can give a significant coding gain without compromising bandwidth efficiency, by the concepts of signal set partition and trellis coding scheme. It is also known that block-coded modulation (BCM) can be used to approach closely the maximum energy saving that can be obtained by using the densest lattice ...

Turbo trellis-coded spatial modulation
2012 IEEE Global Communications Conference (GLOBECOM), 2012In this paper, a turbo trellis-coded spatial modulation (TTCSM) transmission scheme is proposed. In trellis-coded spatial modulation (TCSM) scheme, the information bits used to select the transmit antenna index are encoded. In order to increase the performances of the TCSM scheme, a parallel concatenated encoding scheme can be used. Therefore, the TCSM

Phase ambiguity resolution in trellis-coded modulations
IEEE Transactions on Communications, 1990A rotation detection algorithm for solving the phase ambiguity problem in trellis-coded modulations is proposed. This algorithm is simple to implement and may be an efficient alternative to rotationally invariant codes. Its performance has been investigated by simulation and appears promising. >

Turbo coding applied to pragmatic trellis-coded modulation
IEEE Communications Letters, 2000This letter reports the application of the powerful turbo coding technique combined with the bandwidth efficient method known as trellis-coded modulation (TCM). Implemented as a simple modification of pragmatic TCM, our turbo-coded pragmatic TCM system achieved coding gains of 1-2 dB in simulations relative to pragmatic TCM.

Dirty paper coding using trellis-coded modulation
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013Although the information theoretic result referred to as “dirty paper coding” [1] has been known for quite a while, it has not led to schemes that look attractive enough for real-life communication systems. In a companion paper [2], we presented the concept of sum codes and showed how they provide a convenient platform for interference suppression via ...
