Convergence of iterative decoding

open access: yesElectronics Letters, 1999
A novel method for visualising the convergence behaviour of iterative decoding schemes is proposed. Each constituent decoder is represented by a mutual information transfer characteristic which describes the flow of extrinsic information through the soft in/soft out decoder.

Joint source-channel iterative decoding based on hidden markov model

open access: yesTongxin xuebao, 2006
A joint source-channel decoding algorithm using source parameters which were estimated by the soft output of Turbo code with Baum-Welch reestimated algorithm was proposed.

Turbo DPSK in Bi-directional Relaying

open access: yes, 2013
In this paper, iterative differential phase-shift keying (DPSK) demodulation and channel decoding scheme is investigated for the Joint Channel decoding and physical layer Network Coding (JCNC) approach in two-way relaying systems.

Extrinsic Information Modification in the Turbo Decoder by Exploiting Source Redundancies for HEVC Video Transmitted Over a Mobile Channel

open access: yesIEEE Access, 2016
An iterative turbo decoder-based cross layer error recovery scheme for compressed video is presented in this paper. The soft information exchanged between two convolutional decoders is reinforced both by channel coded parity and video compression ...

Trapping Set Enumerators for Repeat Multiple Accumulate Code Ensembles

open access: yes, 2009
The serial concatenation of a repetition code with two or more accumulators has the advantage of a simple encoder structure. Furthermore, the resulting ensemble is asymptotically good and exhibits minimum distance growing linearly with block length ...

Experimental Demonstration of 16-QAM DD-SEFDM With Cascaded BPSK Iterative Detection

open access: yesIEEE Photonics Journal, 2016
To simplify the complexity of a spectrally efficient frequency-division multiplexing (SEFDM) system, cascaded binary-phase-shift-keying iterative detection (CBID) is proposed for square $M$-ary quadrature-amplitude-modulation (M-QAM) SEFDM as the first ...

On Decoding Schemes for the MDPC-McEliece Cryptosystem [PDF]

open access: yes, 2018
Recently, it has been shown how McEliece public-key cryptosystems based on moderate-density parity-check (MDPC) codes allow for very compact keys compared to variants based on other code families. In this paper, classical (iterative) decoding schemes for

Evaluation of MMSE-Based Iterative Soft Detection Schemes for Coded Massive MIMO System

open access: yesIEEE Access, 2019
There have been a number of researches on soft iterative detection and decoding scheme for coded multiple-input-multiple-output (MIMO) systems. Minimum mean square error (MMSE)-based detection schemes were often considered for massive MIMO systems, due ...

Novel low-delay scheme for parallel Turbo decoding

open access: yesTongxin xuebao, 2011
In order to decrease decoding delay because of the iterative and recursive computation in MAP class algo-rithms,a novel parallel decoding scheme was proposed.The key of the novel scheme was to design a novel collision-free(CF) interleaver.After the ...
