摘要 基于数学分析中著名的不动点原理 ,对于低密度纠删码本文证明了其删除错误译码算法稳定收敛的一充分条件 .而且指出此条件优于现有的稳定收敛条件 . Based on the known principle of fixed points in mathematical analysis,a sufficient convergence condition of erasure decoding algorithm for erasure codes is shown.Moreover,it is pointed out that this convergence condition is weaker than the convergence condition available.Finally,some upper bounds on the maximum tolerable loss fraction δ for which their decoding is successful are shown given a degree distribution pair.
