Ternary Trellis Coded Modulation [PDF]

IEEE Access, 2019
Ternary trellis coded modulation (TTCM) is introduced. This combines triangular signal constellations with ternary convolutional codes. The performance of TTCM is presented and compared with binary trellis coded modulation (BTCM) which employs square ...

Bandwidth-efficient and reliable communication in smart grid systems for modern energy networks using Trellis and Turbo Trellis Coded Modulation [PDF]

Scientific Reports
Smart Grids rely on robust communication infrastructures to monitor, control, and stabilize information in real time across geographically distributed energy resources. Trellis Coded Modulation (TCM) is a well-established technique for improving spectral

Trellis Coded Spatial Modulation [PDF]

IEEE Transactions on Wireless Communications, 2010
Trellis coded modulation (TCM) is a well known scheme that reduces power requirements without any bandwidth expansion. In TCM, only certain sequences of successive constellation points are allowed (mapping by set partitioning). The novel idea in this paper is to apply the TCM concept to the antenna constellation points of spatial modulation (SM).

Trellis-Coded Modulation-Enabled Probabilistic Shaping With Simplified Viterbi Decoder for Bandwidth-Limited IMDD Systems

IEEE Photonics Journal, 2023
In this article, trellis-coded modulation-enabled probabilistic shaping (TEPS) scheme with a simplified Viterbi decoder is proposed. Trellis-coded modulation (TCM) is embedded in the probabilistic shaping (PS) technique to improve the performance of PS ...

Studying and Modeling the Performance of the TCM-STBC Systems in the Rayleigh Channel

Journal of Telecommunications and Information Technology, 2021
Multiple-input multiple-output (MIMO) systems will play an important role in future generations of wireless networks. Space-time block code (STBC) and space-time trellis code (STTC) are two techniques that may be used in multiantenna radio systems. This

Trellis coded modulation to improve dirty paper trellis watermarking [PDF]

SPIE Proceedings, 2007
Lattice codes and quantization-based techniques have received considerable attention as a method of digital watermarking with side information. However, these algorithms are also recognized to be highly sensitive to common signal processing primitives such as valuemetric scaling, e.g. changes in volume of a song, or re-quantization, e.g.

A Novel Concatenated Coded Modulation Based on GFDM for Access Optical Networks

IEEE Photonics Journal, 2018
In this paper, we proposed a novel concatenated coded modulation composed of adaptive turbo code with trellis-coded modulation (ATTCM) that is based on generalized frequency division multiplex (GFDM) system.

The peculiarity of signal-coded-construction with higher stability of fading in decameter channel

Физика волновых процессов и радиотехнические системы, 2020
The signal-coded-construction with higher stability of fading is are presented. The base of this construction is sequential (mono-carrier) transmission-method, turbo-trellis-coded-modulation and high specific keying rate.
