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.

Space-Time Turbo Coded Modulation: Design and Applications
EURASIP 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.

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 ...
