Adaptive Turbo Trellis Coded Modulation Aided Distributed Space-Time Trellis Coding for Cooperative Communications [PDF]
2010 IEEE 71st Vehicular Technology Conference, 2010 In this contribution, we propose an adaptive Turbo Trellis Coded Modulation (TTCM) aided Distributed Space-Time Trellis Coding (STTC) scheme for cooperative communication over quasi-static Rayleigh fading channels. An adaptive TTCM (ATTCM) scheme is employed by the source node during the first transmission period for reliably conveying the source bits ...

Combination of turbo equalisation and Turbo Trellis-coded modulation with low complexity
IET Communications, 2007 A novel low-complexity scheme of Turbo Trellis-coded modulation (TCM) iterative equalisation and decoding is presented, which serially concatenates a soft-input-soft-output equaliser and symbol-by-symbol Turbo TCM (TTCM) decoder through an iterative process in order to realise iterative equalisation and decoding process.

An Effective Error Correction Scheme for Arithmetic Coding
Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 We propose an effective error correction technique for arithmetic coding with forbidden symbol. By predicting the occurrence of the subsequent forbidden symbols, the forbidden region is actually expanded and theoretically, a better error correction performance can be achieved. Moreover, a generalized stack algorithm is exploited to detect the forbidden

The Journal of Engineering, Volume 2014, Issue 8, Page 391-398, August 2014., 2014 This study presents research that supplements and extends the previous works on design of space‐time fully systematic unpunctured (FSU) serial concatenation of quadratic interleaved codes (SCQICs). The requirements for efficient design of the forward error correction (FEC) codecs motivated potential information‐theoretic studies for enjoying the ...

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

A Dimension Distance-Based SCMA Codebook Design
IEEE Access, 2017 For sparse code multiple access (SCMA) with traditional codebooks, the initial information of message passing algorithm (MPA) receiver is easily susceptible to noise and multipath fading, and the convergence reliability of the first detected user in each
