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

EURASIP 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 ...

Low-Density Arrays of Circulant Matrices: Rank and Row-Redundancy Analysis, and Quasi-Cyclic LDPC Codes

, 2012
This paper is concerned with general analysis on the rank and row-redundancy of an array of circulants whose null space defines a QC-LDPC code. Based on the Fourier transform and the properties of conjugacy classes and Hadamard products of matrices, we ...

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]

, 2013
Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.

Circulant Arrays on Cyclic Subgroups of Finite Fields: Rank Analysis and Construction of Quasi-Cyclic LDPC Codes

, 2010
This paper consists of three parts. The first part presents a large class of new binary quasi-cyclic (QC)-LDPC codes with girth of at least 6 whose parity-check matrices are constructed based on cyclic subgroups of finite fields.

Comparison of Polar Decoders with Existing Low-Density Parity-Check and Turbo Decoders

, 2017
Polar codes are a recently proposed family of provably capacity-achieving error-correction codes that received a lot of attention. While their theoretical properties render them interesting, their practicality compared to other types of codes has not ...

Optimized Puncturing of the Check Matrix for Rate-Compatible LDPC Codes

MATEC Web of Conferences, 2018
In the wireless communication system, it is necessary to change the transmitted code word or code rate in real time according to the channel environment, designing and implementing rate compatible codes is of great practical significance.

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

, 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

Mutual Information-Maximizing Quantized Belief Propagation Decoding of Regular LDPC Codes

, 2020
In mutual information-maximizing lookup table (MIM-LUT) decoding of low-density parity-check (LDPC) codes, table lookup operations are used to replace arithmetic operations.
