Joint equalization and decoding with per-survivor processing based on super-trellis in time-varying underwater acoustic channels [PDF]

open access: yesJASA Express Letters
This Letter proposes a low-complexity joint equalization and decoding reception scheme based on super-trellis per-survivor processing, making it possible to apply maximum likelihood sequence estimation in high-order underwater acoustic communications ...

A Novel Concatenated Coded Modulation Based on GFDM for Access Optical Networks

open access: yesIEEE 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.

The peculiarity of signal-coded-construction with higher stability of fading in decameter channel

open access: yesФизика 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.

A Soft-Output STBC Decoder for Aeronautical Telemetry

open access: yesJournal of Telecommunications and Information Technology, 2020
Alamouti encoding is a well-known space time block encoding technique used to improve the received signal quality in Rayleigh fading channels. In aeronautical telemetry, this encoding technique is applied to shaped offset quadrature phase shift keying ...

Turbo Trellis Coded Modulation (TTCM) with Imperfect Phase Reference

open access: yesElectrica, 2019
In this paper, we investigate the performance of Turbo Trellis Coded Modulation (TTCM) over AWGN, and Rician channels and assume that phase disturbance is available.

Golden Space–Time Trellis Coded Modulation [PDF]

open access: yesIEEE Transactions on Information Theory, 2007
In this paper, we present a concatenated coding scheme for a high rate $2\times 2$ multiple-input multiple-output (MIMO) system over slow fading channels. The inner code is the Golden code \cite{Golden05} and the outer code is a trellis code. Set partitioning of the Golden code is designed specifically to increase the minimum determinant.

Improving Capacity in LMDS Networks Using Trellis-Coded Modulation

open access: yesEURASIP Journal on Wireless Communications and Networking, 2004
Local multipoint distribution systems (LMDS), which are operating worldwide in the frequency range of 26 to 43 GHz, have large bandwidths of 0.1 up to 2 GHz but a limited area coverage of a few kilometers only.

Space-Time Turbo Coded Modulation: Design and Applications

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
A design method for recursive space-time trellis codes and parallel-concatenated space-time turbo coded modulation is proposed that can be applied to an arbitrary existing space-time trellis code.
