Turbo Trellis-Coded Differential Chaotic Modulation

IEEE Transactions on Circuits and Systems II: Express Briefs, 2018
In this brief, a novel turbo trellis-coded differential chaotic modulation (TTC-DCM) system is proposed, where parallel concatenated trellis codes are combined with the ${M}$ -ary differential chaotic shift keying ( ${M}$ -ary DCSK) scheme.

EXIT Charts for Turbo Trellis-Coded Modulation

IEEE Communications Letters, 2004
In this letter, we extend the previously proposed extrinsic information transfer charts (EXIT) method to the analysis of the convergence of turbo codes to turbo trellis-coded modulation (TTCM) schemes. The effectiveness of the proposed method is demonstrated through examples.

Design of unpunctured turbo trellis-coded modulation

AEU - International Journal of Electronics and Communications, 2013
Abstract In this paper, the design of newly introduced turbo encoding scheme called ‘Unpunctured Turbo Trellis-Coded Modulation’ (UTTCM) is exposed. The performance improvement of this encoding scheme is obtained by setting a design criterion for each of its components namely: the search rules of best constituent encoders’ generator polynomials, the ...

A nonpragmatic approach to turbo trellis coded modulations

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
A novel approach to combine turbo coding and high level modulation is introduced. Systematic trellis coded M-ary modulations are used as constituent codes. This scheme is a direct generalization to M-ary modulations of binary turbo codes. As a result, the whole iterative process is performed at M-ary symbol level.

Turbo coding applied to pragmatic trellis-coded modulation

IEEE Communications Letters, 2000
This 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.
