In this paper, we study the stopping sets, stopping distance and stopping redundancy for binary linear codes. stopping redundancy is a new concept proposed by schwartz and vardy recently for evaluating the performance of a linear code under iterative decoding over a binary erasure channel. since the exact value of stopping redundancy is difficult to obtain in general, good lower and upper bounds are important
近年來，迭代譯碼的性能分析是低密度校驗ldpc碼研究領域的熱點問題之一， di等人在2001年指出：迭代譯碼在二元刪除通道bec中的性能可以由ldpc碼的停止集stopping set完全刻畫。 -
We obtain a new general upper bound on the stopping redundancy of binary linear codes which improves the corresponding results of schwartz and vardy
