Multisource SWIPT-based coded cooperation:rate compatible codes and codeword splitting protocol

open access: yesEURASIP Journal on Wireless Communications and Networking, 2020
To achieve a high reliable and energy-saving green communication, we investigate a multisource simultaneous wireless information and power transfer (SWIPT)-based coded cooperation where the relay can realize information decoding and energy harvesting ...

Iterative Soft Input Soft Output Decoding of Reed-Solomon Codes by Adapting the Parity Check Matrix [PDF]

open access: yes, 2005
An iterative algorithm is presented for soft-input-soft-output (SISO) decoding of Reed-Solomon (RS) codes. The proposed iterative algorithm uses the sum product algorithm (SPA) in conjunction with a binary parity check matrix of the RS code.

A Construction of Optimal $(r,\delta)$ -Locally Recoverable Codes

open access: yesIEEE Access, 2019
Locally recoverable codes (LRCs) play a significant role in distributed and cloud storage systems. The key ingredient for constructing such optimal LRCs is to characterize the parity-check matrix for LRCs.

Refined Upper Bounds on Stopping Redundancy of Binary Linear Codes [PDF]

open access: yes, 2015
The $l$-th stopping redundancy $\rho_l(\mathcal C)$ of the binary $[n, k, d]$ code $\mathcal C$, $1 \le l \le d$, is defined as the minimum number of rows in the parity-check matrix of $\mathcal C$, such that the smallest stopping set is of size at least

Encoding of QC-LDPC Codes of Rank Deficient Parity Matrix

open access: yesJournal of Engineering, 2016
the encoding of long low density parity check (LDPC) codes presents a challenge compared to its decoding. The Quasi Cyclic (QC) LDPC codes offer the advantage for reducing the complexity for both encoding and decoding due to its QC structure.

Carrier phase recovery of LDPC-coded systems based on the likelihood difference algorithm

open access: yesEURASIP Journal on Advances in Signal Processing, 2023
The problem of blind phase offset recovery of low density parity-check (LDPC)-coded systems is considered in this paper. We propose a new algorithm of phase offset estimation that involves the computation and maximization of a likelihood difference (LD ...

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length

open access: yes, 2017
In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...
