Efficient decoding of block turbo codes
Journal of Communications and Networks, 2018 Block turbo codes (BTCs) under iterative decoding are product codes showing excellent performance with reasonable complexity, whose component codes are conventionally decoded in two stages. The Chase algorithm is employed in the first stage to make a list of candidate codewords from the received vector, while the extrinsic information for iterative ...

Recurrent neural network based turbo decoding algorithms for different code rates
Journal of King Saud University: Computer and Information Sciences, 2022 Application of deep learning to error control coding is gaining special attention and neural network architectures on decoding are approached to compare with conventional ones. Turbo codes conventionally use BCJR algorithm for decoding.

Performance of Reed-Solomon block turbo code [PDF]
Proceedings of GLOBECOM'96. 1996 IEEE Global Telecommunications Conference, 2002 Thanks to recent progress in the iterative decoding of concatenated codes, several new fields of investigation have appeared. In this paper, we present a first approach of the iterative decoding of Reed-Solomon (RS) product codes: "Turbo codes RS". Two methods to construct RS product codes are given.

Performance Analysis and Improvement for VAMP Soft Frequency-Domain Equalizers
IEEE Access, 2019 The vector approximate message passing (VAMP) soft frequency-domain equalizer (SFDE) has been proposed for turbo equalization. It consists of an inner soft equalizer (ISE) and an inner soft slicer (ISS), which iteratively exchange block-wise extrinsic ...

Low-Complexity Decoding of Block Turbo-Coded System with Antenna Diversity
EURASIP Journal on Advances in Signal Processing, 2003 The goal of this paper is to reduce the decoding complexity of space-time block turbo-coded system with low performance degradation. Two block turbo-coded systems with antenna diversity are considered.

Combined Distributed Turbo Coding and Space Frequency Block Coding Techniques
EURASIP Journal on Wireless Communications and Networking, 2010 The distributed space-time (frequency) coding and distributed channel turbo coding used independently represent two cooperative techniques that can provide increased throughput and spectral efficiency at an imposed maximum Bit Error Rate (BER) and delay required from the new generation of cellular networks.

Turbo Equalization Of Nonlinear ISI-channels Using High Rate FEC Codes [PDF]
Advances in Radio Science, 2005 Turbo equalization is a widely known method to cope with low signal to noise ratio (SNR) channels corrupted by linear intersymbol interference (ISI) (Berrou and Galvieux, 1993; Hagenauer et al., 1997).
