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 ...

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).

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

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.

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.
