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 ...

Recurrent neural network based turbo decoding algorithms for different code rates

open access: yesJournal 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]

open access: yesProceedings 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

open access: yesIEEE 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 ...

Forward and backward RLS-DDCE processing in MIMO-OFDM spatial multiplexing receivers [PDF]

open access: yesAdvances in Radio Science, 2010
In this paper we present a novel approach in frequency domain channel estimation technique. Our proposal is based on the recursive least squares (RLS) algorithm combined with the decision making process called decision directed channel estimation (RLS ...

Turbo Equalization Of Nonlinear ISI-channels Using High Rate FEC Codes [PDF]

open access: yesAdvances 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).

Network‐turbo‐coding‐based cooperation with distributed space‐time block codes [PDF]

open access: yesTransactions on Emerging Telecommunications Technologies, 2014
AbstractIn this paper, we propose a scheme to improve the performance of turbo‐coded two‐user cooperative uplink transmission. In the proposed scheme, each user transmits its partner's second parity frame in addition to its own, using a network‐coded combination, which is further protected by a space‐time block code. The proposed system is simulated in

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

open access: yesMolecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve
