A decoding algorithm for finite-geometry LDPC codes
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2005年 第3期53卷 415-421页
作者: Liu, ZY Pados, DA SUNY Buffalo Dept Elect Engn Buffalo NY 14260 USA
In this paper, we develop a new low-complexity algorithm to decode low-density parity-check (LDPC) codes. The developments are oriented specifically toward low-cost, yet effective, decoding of (high-rate) finite-geome... 详细信息

Self-compensation technique for simplified belief-propagation algorithm
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2007年 第6期55卷 3061-3072页
作者: Liao, Yen-Chin Lin, Chien-Ching Chang, Hsie-Chia Liu, Chih-Wei Natl Chiao Tung Univ Dept Elect Engn Hsinchu 30039 Taiwan
The min-sum algorithm is the most common method to simplify the belief-propagation algorithm for decoding low-density parity-check (LDPC) codes. However, there exists a performance gap between the min-sum and belief-p... 详细信息

Low-density parity-check lattices: Construction and decoding analysis
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2006年 第10期52卷 4481-4495页
作者: Sadeghi, Mohammad-Reza Banihashemi, Amir H. Panario, Daniel Amirkabir Univ Technol Fac Math & Comp Sci Tehran Iran Carleton Univ Dept Syst & Comp Engn BCWS Ctr Ottawa ON K1S 5B6 Canada Carleton Univ Sch Math & Stat Ottawa ON K1S 5B6 Canada
Low-density parity-check codes (LDPC) can have an impressive performance under iterative decoding algorithms. In this paper we introduce a method to construct high coding gain lattices with low decoding complexity bas... 详细信息

High performance short-block binary regular LDPC codes
收藏 引用
ALEXANDRIA ENGINEERING JOURNAL 2018年 第4期57卷 2633-2639页
作者: Mostari, Latifa Taleb-Ahmed, Abdelmalik Hassiba Benbouali Univ Chlef Fac Technol Dept Elect Chlef Algeria Univ Valenciennes & Hainaut Combresis LAMIH UMR CNRS 8201 Valenciennes France
LDPC code shows a good performance with long-block codes. However, certain channels are constrained to use short-block codes due to latency. Therefore, concatenated LDPC codes with iterative decoding is a good choice ... 详细信息

On Decoding Irregular Tanner Codes With Local-Optimality Guarantees
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2014年 第1期60卷 191-211页
作者: Halabi, Nissim Even, Guy Tel Aviv Univ Sch Elect Engn IL-69978 Tel Aviv Israel
We consider decoding of binary linear Tanner codes using message-passing iterative decoding and linear-programming (LP) decoding in memoryless binary-input output-symmetric (MBIOS) channels. We present new certificate... 详细信息

Resource Allocation via Message Passing
收藏 引用
INFORMS JOURNAL ON COMPUTING 2011年 第2期23卷 205-219页
作者: Moallemi, Ciamac C. Van Roy, Benjamin Columbia Univ Grad Sch Business New York NY 10027 USA Stanford Univ Dept Management Sci & Engn Stanford CA 94305 USA
We propose a message-passing paradigm for resource allocation problems. This serves to connect ideas from the message-passing literature, which has primarily grown out of the communications, statistical physics, and a... 详细信息

Cost-effective variable node using thermalcode addition for LDPC decoders
收藏 引用
IEICE ELECTRONICS EXPRESS 2011年 第23期8卷 1948-1953页
作者: Yang, Po-Hui Liu, Jia-Ping Natl Yunlin Univ Sci & Technol Dept Elect Engn Yunlin 640 Taiwan
The current paper presents thermalcode addition technology as applied to an LDPC decoder to replace a variable node unit in the traditional adder. The proposed irregular quantization of thermalcode addition can genera... 详细信息
