EXIT-Chart Aided Design of Irregular Multiple-Rate Quantum Turbo Block Codes

open access: yesIEEE Access, 2023
We propose a novel quantum turbo short-block code, which subsumes multiple-rate quantum short-block codes (MR-QSBCs) as the outer codes and a quantum unity-rate code (QURC) as the inner code. The proposed design is denoted as MR-QSBC-QURC.

Application of syndrome based Turbo decoding with adaptive computational complexity in LTE downlink [PDF]

open access: yesAdvances in Radio Science, 2012
This paper describes the application of an adaptive complexity decoder for the Long Term Evolution (LTE) downlink Turbo code. The proposed decoding approach is based on the block syndrome decoding principle and enables adaptive reduction of decoding ...

Efficient decoding of block turbo codes

open access: yesJournal 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 ...

New High Performance Deterministic Interleavers for Turbo Codes

open access: yesAdvances in Electrical and Computer Engineering, 2010
Turbo codes offer extraordinary performance, especially at low signal to noise ratios, due to a low multiplicity of low weight code words. The interleaver design is critical in order to realize an apparent randomness of the code, thus further enhancing

An Efficient Hybrid Decoder for Block Turbo Codes

open access: yesIEEE Communications Letters, 2014
In this letter, an efficient hybrid decoder for block turbo codes (BTCs) is proposed to improve the hybrid BTC decoder developed by Al-Dweik et al. A simple formula for estimating the extrinsic information is first derived. Then the proposed decoder is constructed by modifying the decoder of Al-Dweik et al. using the formula.

DIFFERENT FPGA PRODUCTS BASED IMPLEMENTATION OF LTE TURBO CODE

open access: yesIraqi Journal of Information & Communication Technology, 2020
In the long-term evolution (LTE) physical layer, using turbo code is considered as the paramount one in error-correcting coding. This paper presents an implementation of LTE turbo decoding using the Log- Maximum a posteriori (MAP) algorithm with reduced ...

Threshold Based Iteration Stopping Criterion for Turbo Codes and for Scheme Combining a Turbo Code and a Golden Space-Time Block Code

open access: yesAdvances in Electrical and Computer Engineering, 2014
This paper proposes an iteration stopping criterion for turbo decoding with Benedetto's decoding algorithm based on a posteriori probabilities. This stopping criterion is used in two schemes.
