SOVA-Decoded Serially Concatenated Continuous Phase Modulation System With Markov and Hidden Markov Sources

open access: yesIEEE Access
We design low-complexity bi-directional (forward and backward) modified Soft-Output Viterbi Algorithm (SOVA) decoders to exploit source memory from binary Markov and hidden Markov model (HMM) sources, respectively, for decoding in serially concatenated ...

High performance short-block binary regular LDPC codes

open access: yesAlexandria Engineering Journal, 2018
LDPC code shows a good performance with long-block codes. However, certain channels are constrained to use short-block codes due to latency. Therefore, concatenated LDPC codes with iterative decoding is a good choice to get a good performance ...

Low Complexity Approach for High Throughput Belief-Propagation based Decoding of LDPC Codes

open access: yesAdvances in Electrical and Computer Engineering, 2013
The paper proposes a low complexity belief propagation (BP) based decoding algorithm for LDPC codes. In spite of the iterative nature of the decoding process, the proposed algorithm provides both reduced complexity and increased BER performances as ...

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 ...

Low Complexity Early Stopping Belief Propagation Decoder for Polar Codes

open access: yesIEEE Access
Belief propagation is one of low latency decoding algorithms for polar codes but it requires relatively high decoding complexity due to its inherent iterative decoding nature.

Discriminated Belief Propagation

open access: yes, 2007
Near optimal decoding of good error control codes is generally a difficult task. However, for a certain type of (sufficiently) good codes an efficient decoding algorithm with near optimal performance exists.

Three-Dimensional EXIT Chart Analysis of Iterative Detection Aided Coded Modulation Schemes

open access: yes, 2006
The iterative convergence of iteratively detected coded modulation schemes having different block lengths, decoding complexity and an unequal error protection capability is studied, when communicating over AWGNchannels using 8PSK modulation.

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
