Design of Optimal LDPC Code for the System of MDPSK Concatenated with LDPC Codes
2009 International Conference on Communication Software and Networks, 2009The combined demodulating and decoding algorithm of the system of M-ary Differential Phase-Shift Keying (MDPSK) concatenated with Low-Density Parity Check Codes in AWGN channels is analyzed in this paper. Concentrating on the above algorithm, we propose a design method of optimal LDPC code based on Extrinsic Information Transfer Chart. Meanwhile, as an

A Reconfigurable LDPC Decoder Optimized for 802.11n/ac Applications
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2018This paper presents a high data-rate low-density parity-check (LDPC) decoder, suitable for the 802.11n/ac (WiFi) standard. The innovative features of the proposed decoder relate to the decoding algorithms and the interconnection between the processing ...

The Design of Protograph LDPC Codes as Source Codes in a JSCC System
IEEE Communications Letters, 2018Although joint source-channel coding (JSCC) based on double protograph low-density parity-check (LDPC) codes has been shown to be an excellent solution for wireless communication, the protograph LDPC code for source coding needs to be optimized to ...

An LDPC Approach for Chunked Network Codes
IEEE/ACM Transactions on Networking, 2018Efficient communication through a multi-hop network with packet loss requires random linear network coding schemes with low computation cost and high throughput. In this paper, we propose a low-density parity-check (LDPC)-based framework for constructing

Design of LDPC Codes Based on Multipath EMD Strategies for Progressive Edge Growth
IEEE Transactions on Communications, 2016Low-density parity-check (LDPC) codes are capable of achieving excellent performance and provide a useful alternative for the high-performance applications. However, at medium to high signal-to-noise ratios, an observable error floor arises from the loss

Performance Evaluation of LDPC-LDPC Product Code for next Magnetic Recording Channel
Journal of the Institute of Electronics Engineers of Korea, 2012Two-dimensional product code has been studied for correcting burst errors on the storage systems. An RS-LDPC product code consists of an RS code in horizontal direction and an LDPC code in vertical direction. First, we detect the position of burst errors by using RS code, then LDPC code corrects the errors by using the burst error positions. In storage

Analytical Lower Bound on the Lifting Degree of Multiple-Edge QC-LDPC Codes With Girth 6
IEEE Communications Letters, 2018Multiple-edge protographs have some advantages over single-edge protographs, such as potentially having larger minimum Hamming distance. However, most of results in the literature are related to the construction of single-edge quasi-cyclic low-density ...
