Near-Capacity Turbo Trellis Coded Modulation Design [PDF]

2007 IEEE 66th Vehicular Technology Conference, 2007
Bandwidth efficient parallel-concatenated turbo trellis coded modulation (TTCM) schemes were designed for communicating over uncorrelated Rayleigh fading channels. A symbol-based union bound was derived for analysing the error floor of the proposed TTCM schemes. A pair of in-phase (I) and quadrature-phase (Q) interleavers were employed for interleaving

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

Distributed Turbo Trellis Coded Modulation for Cooperative Communications [PDF]

2009 IEEE International Conference on Communications, 2009
In this contribution, we propose a Distributed Turbo Trellis Coded Modulation (DTTCM) scheme for cooperative communications. The DTTCM scheme is designed based on its decoding convergence with the aid of non-binary Extrinsic Information Transfer (EXIT) charts. The source node transmits TTCM symbols to both the relay and the destination nodes during the

Repeat-punctured turbo trellis-coded modulation [PDF]

IEEE Africon '11, 2011
In this paper repeat-punctured turbo trellis-coded modulation (RPTTCM) is proposed. In RPTTCM, the effect of repeat-puncture is investigated on a TTCM system, repetition of the information bits increases the interleaver size, followed by an appropriate puncturing scheme to maintain the respective code rate.

Bandwidth-efficient turbo trellis-coded modulation using punctured component codes [PDF]

IEEE Journal on Selected Areas in Communications, 1998
We present a bandwidth-efficient channel coding scheme that has an overall structure similar to binary turbo codes, but employs trellis-coded modulation (TCM) codes (including multidimensional codes) as component codes. The combination of turbo codes with powerful bandwidth-efficient component codes leads to a straightforward encoder structure, and ...

Distributed Video Coding using Turbo Trellis Coded Modulation [PDF]

The Visual Computer, 2008
Distributed Video Coding (DVC) has been proposed for increasingly new application domains. This rise is apparently motivated by the very attractive features of its flexibility for building very low cost video encoders and the very high built-in error resilience when applied over noisy communication channels.

Combined trellis-coded modulation and blind turbo equalisation [PDF]

EUROCON'2001. International Conference on Trends in Communications. Technical Program, Proceedings (Cat. No.01EX439), 2002
Per-survivor processing (PSP)-based blind turbo equalization is combined with various coded modulation schemes, which employ combined modulation and channel coding techniques. The proposed method exploits the enhanced data protection offered by either trellis-coded modulation (TCM), bit-interleaved coded modulation (BICM) or turbo-TCM (TTCM) and ...

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.

Combined Source-Channel Coding of Images under Power and Bandwidth Constraints

EURASIP Journal on Advances in Signal Processing, 2007
This paper proposes a framework for combined source-channel coding for a power and bandwidth constrained noisy channel. The framework is applied to progressive image transmission using constant envelope M-ary phase shift key (M-PSK) signaling over an ...
