| Abstract: | 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. |
