Joint trellis coded quantization/modulation

IEEE Transactions on Communications, 1991
A joint source/channel coding system constructed using trellis coded quantization (TCQ) and trellis coded modulation (TCM) is described. Identical trellises are used in the TCQ and TCM systems, and a straightforward mapping of TCQ codewords to TCM symbols is presented which guarantees that Euclidean squared distance in the channel is commensurate with ...

Multiple trellis coded modulation (MTCM)

IEEE Transactions on Communications, 1988
The authors demonstrate a trellis coded modulation technique referred to as multiple trellis coded modulation (MTCM) wherein more than one channel symbol per trellis branch is transmitted. They have found simple two-state trellis codes for symmetric MPSK multiple phase-shift keying and AM modulations that can achieve 3-dB gain over uncoded modulation ...

Trellis coded quadrature spatial modulation

Physical Communication, 2018
Abstract 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-coded modulation with multidimensional constellations

IEEE Transactions on Information Theory, 1987
Trellis-coded modulation schemes using four-, eight-, or 16 -dimensional constellations have a number of potential advantages over the usual two-dimensional schemes: a smaller constituent two-dimensional constellation, easier tolerance to phase ambiguities, and a better trade-off between complexity and coding gain.

Punctured Trellis-Coded Quantization and Modulation

IEEE Transactions on Communications, 2006
We 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 ...
