Trellis coded quadrature spatial modulation
Physical Communication, 2018Abstract In this paper, a novel multiple-input multiple-output (MIMO) transmission scheme called trellis coded quadrature spatial modulation (TC-QSM), is proposed. In the proposed scheme, trellis coded modulation (TCM) principle is applied to the emerging quadrature spatial modulation (QSM) scheme, and a trellis encoder and a QSM mapper are jointly ...

Trellis Coding with Asymmetric Modulations
IEEE Transactions on Communications, 1987Traditionally symmetric signal constellations, i.e., those with uniformly spaced signal points, have been used for both uncoded and coded systems. Although symmetric signal constellations are optimum with no coding, the same is not necessarily true for coded systems. This paper shows that by designing the signal constellations to be asymmetric, one can,

A Pragmatic Approach to Trellis-Coded Modulation
IEEE Communications Magazine, 1989Since the early 1970s, for power-limited applications, the convolutional code constraint length K=7 and rate 1/2, optimum in the sense of maximum free distance and minimum number of bit errors caused by remerging paths at the free distance, has become the de facto standard for coded digital communication.

Trellis Code Design for Spatial Modulation
2011 IEEE International Conference on Communications (ICC), 2011In this paper, we propose a novel MIMO transmission scheme, called trellis coded spatial modulation (TC-SM) in which the trellis (convolutional) encoder and the spatial modulation (SM) mapper are jointly designed similar to the conventional trellis coded modulation (TCM).

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.

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.

Punctured Trellis-Coded Quantization and Modulation
IEEE Transactions on Communications, 2006We propose a punctured trellis-coded quantization (PTCQ) scheme as the dual of a known punctured trellis-coded modulation (PTCM) scheme, and then generalize a combined trellis-coded quantization/modulation (TCQ/TCM) scheme to a combined PTCQ/PTCM scheme, with rates optimally allocated between source coding and channel coding to match the given channel ...

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 ...

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 ...

Noncoherently Non-Catastrophic Trellis Coded Modulation
IEEE Transactions on Communications, 2011In this paper, we propose a noncoherently non-catastrophic trellis-coded modulation scheme, in which the transmitter includes a differential encoder, a rotator, an inverse signal mapper, a convolutional encoder and a signal mapper. We present examples of the proposed scheme including MPSK (M-ary phase shift keying), QAM (quadrature-amplitude modulation)
