DISCRETE APPLIED MATHEMATICS 2003年 第1期128卷 293-303页
作者: Soljanin, E Offer, E Lucent Technol Bell Labs Murray Hill NJ 07974 USA Tech Univ Munich Inst Comm Eng D-80290 Munich Germany
We introduce a group algebra formulation for bit-optimal decoding of binary block codes. We use this new framework to give a simple algebraic proof that Pearl's and Gallager's belief propagation decoding algor... 详细信息

作者: Soljanin, E. Offer, E. Bell Laboratories Lucent Technologies Murray Hill NJ 07974 United States Munich University of Technology Institute of Comm. Eng. 80290 Munich Germany
After the rediscovery of low-density parity-check (LDPC) codes, their decoding algorithms have been studied by mathematical tools pertinent more to computer science than the conventional algebraic coding theory. We pr... 详细信息
