题目： Stopping Set Distributions of Linear Codes
报告人：符方伟 教授 （南开大学陈省身数学研究所）
摘要: Stopping sets and stopping set distribution of a linear code are used to determine the performance of this code under iterative decoding over a binary erasure channel.We study stopping sets, stopping set distributions and BEC-optimal parity-check matrices of binary linear codes. Using finite geometry in combinatorics, we obtain BEC-optimal parity-check matrices and then determine the stopping set distributions for the Simplex codes, the Hamming codes, the first order Reed-Muller codes, and the extended Hamming codes．We also present some results on the stopping sets of algebraic geometry codes and finite geometry based LDPC codes.
