Performance and Complexity Evaluation of Iterative Receiver for Coded MIMO‐OFDM Systems
Mobile Information Systems, Volume 2016, Issue 1, 2016., 2016 Multiple‐input multiple‐output (MIMO) technology in combination with channel coding technique is a promising solution for reliable high data rate transmission in future wireless communication systems. However, these technologies pose significant challenges for the design of an iterative receiver.

XOR‐FREE Implementation of Convolutional Encoder for Reconfigurable Hardware
International Journal of Reconfigurable Computing, Volume 2016, Issue 1, 2016., 2016 This paper presents a novel XOR‐FREE algorithm to implement the convolutional encoder using reconfigurable hardware. The approach completely removes the XOR processing of a chosen nonsystematic, feedforward generator polynomial of larger constraint length.

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.

Distributed Source-coding, Channel-coding and Modulation for Cooperative Communications [PDF]
, 2010 In this contribution, we propose a novel Distributed Source-coding, Channel-coding and Modulation (DSCM) scheme for cooperative communications. The proposed DSCM scheme is designed for ensuring the decoding convergence of its constituent component codes,

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

Reduced-complexity syndrome-based TTCM decoding [PDF]
, 2013 The iterative decoder of Turbo Trellis Coded Modulation (TTCM) exchanges extrinsic information between the constituent TCM decoders, which imposes a high computational complexity at the receiver. Therefore we conceive the syndrome-based block decoding of
