Simple stopping criterion for min-sum iterative decoding algorithm
收藏 引用
ELECTRONICS LETTERS 2001年 第25期37卷 1530-1531页
作者: Heo, J Chung, K Chugg, KM Univ So Calif Dept Elect Engn Syst Commun Sci Inst Los Angeles CA 90089 USA
A simple stopping criterion for iterative decoding based on min-sum processing is presented. While most stopping criteria suggested in the literature are based on cross entropy (CE) and its simplification, the propose... 详细信息

IEEE TRANSACTIONS ON COMMUNICATIONS 2003年 第8期51卷 1229-1232页
作者: Bosco, G Montorsi, G Benedetto, S Politecn Torino Dipartimento Elettron I-10129 Turin Italy
A new hard iterative decoding algorithm to decode the serial concatenation of two block codes separated by an inter-leaver is presented. The new scheme is based on the use of erasures as a sort of extrinsic informatio... 详细信息

IEEE COMMUNICATIONS LETTERS 2009年 第7期13卷 531-533页
作者: Wang, Xiuni Ma, Xiao Sun Yat Sen Univ Dept Elect & Commun Engn Guangzhou 510275 Peoples R China
Given the Tanner graph of a generalized low-density parity-check (GLDPC) code, the decoding complexity is mainly dominated by the decoding algorithm of subcodes. In this paper, we propose a class of GLDPC codes with f... 详细信息

IEEE International Symposium on Information Theory
作者: Bokolamulla, D Aulin, T Chalmers Univ Technol Dept Comp Engn SE-41296 Gothenburg Sweden
We propose a new reduced-complexity iterative decoding algorithm. The main concept is to approximate the a posteriori probabilities (APP) by a set of few sequences, and to reduce the size of this set with iterations. ... 详细信息
