Turbo-Coded Adaptive Modulation Versus Space–Time Trellis Codes for Transmission Over Dispersive Channels [PDF]
IEEE Transactions on Wireless Communications, 2004 Decision feedback equalizer (DFE)-aided turbocoded wideband adaptive quadrature amplitude modulation (AQAM) is proposed, which is capable of combating the temporal channel quality variation of fading channels. A procedure is suggested for determining 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 ...

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.

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

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.
