Iterative Detection and Decoding Algorithms for MIMO Systems in Block-Fading Channels Using LDPC Codes [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2015
We propose iterative detection and decoding (IDD) algorithms with low-density parity-check (LDPC) codes for multiple-input multiple-output (MIMO) systems operating in block-fading and fast Rayleigh fading channels.

A Low Complexity Iterative Channel Estimation and Decoding Receiver Based on Reed-Solomon PTA

open access: yesIEEE Access, 2016
A low-complexity iterative channel estimation and Reed-Solomon (RS) decoding receiver is developed. The joint channel estimation and decoding receiver is based on the linear minimum mean square error (LMMSE) channel estimation technique and the recently ...

Vectorial Decoding Algorithm for Fast Correlation Attack and Its Applications to Stream Cipher Grain-128a

open access: yesIACR Transactions on Symmetric Cryptology, 2022
Fast correlation attack, pioneered by Meier and Staffelbach, is an important cryptanalysis tool for LFSR-based stream cipher, which exploits the correlation between the LFSR state and key stream and targets at recovering the initial state of LFSR via a ...

Iterative detection and decoding for SCMA systems with LDPC codes [PDF]

open access: yesInternational Conference on Wireless Communications and Signal Processing, 2015
Sparse code multiple access (SCMA) is a promising multiplexing approach to achieve high system capacity. In this paper, we develop a novel iterative detection and decoding scheme for SCMA systems combined with Low-density Parity-check (LDPC) decoding. In

On the Minimum Distance of Generalized Spatially Coupled LDPC Codes [PDF]

open access: yes, 2013
Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes.

Approaching Capacity at High-Rates with Iterative Hard-Decision Decoding [PDF]

open access: yes, 2016
A variety of low-density parity-check (LDPC) ensembles have now been observed to approach capacity with message-passing decoding. However, all of them use soft (i.e., non-binary) messages and a posteriori probability (APP) decoding of their component ...

Iterative decoding for MIMO channels via modified sphere decoding [PDF]

open access: yes, 2004
In recent years, soft iterative decoding techniques have been shown to greatly improve the bit error rate performance of various communication systems. For multiantenna systems employing space-time codes, however, it is not clear what is the best way to ...

Deterministic Non-Autoregressive Neural Sequence Modeling by Iterative Refinement [PDF]

open access: yesConference on Empirical Methods in Natural Language Processing, 2018
We propose a conditional non-autoregressive neural sequence model based on iterative refinement. The proposed model is designed based on the principles of latent variable models and denoising autoencoders, and is generally applicable to any sequence ...

Iterative Pseudo-Labeling for Speech Recognition [PDF]

open access: yesInterspeech, 2020
Pseudo-labeling has recently shown promise in end-to-end automatic speech recognition (ASR). We study Iterative Pseudo-Labeling (IPL), a semi-supervised algorithm which efficiently performs multiple iterations of pseudo-labeling on unlabeled data as the ...

Erasure Codes with a Banded Structure for Hybrid Iterative-ML Decoding [PDF]

open access: yes, 2009
This paper presents new FEC codes for the erasure channel, LDPC-Band, that have been designed so as to optimize a hybrid iterative-Maximum Likelihood (ML) decoding.
