Iterative Decoding of Serial Concatenated Convolutionally Encoded Signals over Frequency Selective Fading Channels

open access: yesJournal of Engineering and Sustainable Development, 2007
Serial concatenated convolutional coding with iterative decoding is examined for data transmission employing BFSK (binary frequency shift keying) modulation and non-coherent detection receiver.

Increasing throughput of iterative decoders

open access: yesElectronics Letters, 2001
Decoding concatenated codes with an iterative decoder including a stopping criterion saves power compared to decoding with a fixed number of iterations. In this work the throughput of the decoder is also increased. This is achieved by using additional buffers at the decoder input and a modified stopping criterion.

A study on acceleration of SP decoder using reliability of recording sequence by neural network based on parity check result in SMR system

open access: yesAIP Advances
We study signal processing methods to realize ultra-high-density hard disk drives (HDDs). Among them, we have applied the neural network to improve decoding performance in low-density parity-check (LDPC) coding and iterative decoding in the shingled ...

Generalized reliability-based syndrome decoding for LDPC codes [PDF]

open access: yesarXiv, 2007
Aiming at bridging the gap between the maximum likelihood decoding (MLD) and the suboptimal iterative decodings for short or medium length LDPC codes, we present a generalized ordered statistic decoding (OSD) in the form of syndrome decoding, to cascade with the belief propagation (BP) or enhanced min-sum decoding.

Iterative Decoding of Turbo Codes

open access: yesJournal of Advanced College of Engineering and Management, 2018
<p><strong> </strong>This paper presents a Thesis which consists of a study of turbo codes as an error-control Code and the software implementation of two different decoders, namely the Maximum a Posteriori (MAP), and soft- Output Viterbi Algorithm (SOVA) decoders. Turbo codes were introduced in 1993 by berrouet at [2] and are perhaps

Iterative Bounded Distance Decoding of Product Codes with Scaled Reliability [PDF]

open access: yesarXiv, 2018
We propose a modified iterative bounded distance decoding of product codes. The proposed algorithm is based on exchanging hard messages iteratively and exploiting channel reliabilities to make hard decisions at each iteration. Performance improvements up to 0.26 dB are achieved.

Study of equivalent point-to-point transmission model for coded relay cooperations

open access: yesTongxin xuebao, 2012
LDPC-coded relay cooperation and its joint iterative decoding based on the bi-layer Tanner graph were investigated.The coded relay cooperation becomed an equivalent and relatively simple point-to-point transmission model by introducing the notation of ...

Anti-Cycle-Slip LDPC Decoding Algorithm for BPSK System

open access: yesDianxin kexue, 2014
When cycle-slip occurs in BPSK modulation system, sign of information sequence which is input of LDPC decoder is opposite to the original one. This problem will lead to decoder failure.
