Joint space-time trellis code detection and MIMO equalisation via particle filtering [PDF]

open access: yes, 2004
In this contribution we address the problem of MIMO equalisation and transmit diversity. More specifically, we develop a method that jointly decodes space time trellis coded modulation (STTCM) encoded signals and equalises the MIMO channels.

Two‐Dimensional Iterative Processing for DAB Receivers Based on Trellis‐Decomposition

open access: yesJournal of Electrical and Computer Engineering, Volume 2012, Issue 1, 2012., 2012
We investigate iterative trellis decoding techniques for DAB, with the objective of gaining from processing 2D‐blocks in an OFDM scheme, that is, blocks based on the time and frequency dimension, and from trellis decomposition. Trellis‐decomposition methods allow us to estimate the unknown channel phase since this phase relates to the sub‐trellises. We

Turbo Trellis-Coded Hierarchical-Modulation Assisted Decode-and-Forward Cooperation [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2015
Hierarchical modulation (HM), which is also known as layered modulation, has been widely adopted across the telecommunication industry. Its strict backward compatibility with single-layer modems and its low complexity facilitate the seamless upgrading of wireless communication services.

VLSI Architectures for Sliding‐Window‐Based Space‐Time Turbo Trellis Code Decoders

open access: yesJournal of Electrical and Computer Engineering, Volume 2012, Issue 1, 2012., 2012
The VLSI implementation of SISO‐MAP decoders used for traditional iterative turbo coding has been investigated in the literature. In this paper, a complete architectural model of a space‐time turbo code receiver that includes elementary decoders is presented.

Distributed Source Coding and Its Applications in Relaying-Based Transmission

open access: yesIEEE Access, 2016
Distributed source coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. DSC has numerous promising applications ranging from reduced-complexity handheld video communications to ...

SVD‐Aided Power Allocation and Iterative Detection Scheme for Turbo‐BLAST System with Imperfect Channel State Information

open access: yesInternational Journal of Antennas and Propagation, Volume 2011, Issue 1, 2011., 2011
A new technique that combines adaptive power allocation and iterative detection based on singular value decomposition (SVD) is introduced for the modified Turbo‐BLAST system with imperfect channel state information (I‐CSI). At the transmitter, in order to maximize the capacity performance, the MIMO channel is decomposed into several parallel eigen ...

Space-Time Trellis and Space-Time Block Coding Versus Adaptive Modulation and Coding Aided OFDM for Wideband Channels

open access: yes, 2006
—The achievable performance of channel coded spacetime trellis (STT) codes and space-time block (STB) codes transmitted over wideband channels is studied in the context of schemes having an effective throughput of 2 bits/symbol (BPS) and 3 BPS.
