For a linear code C, the stopping redundancy of C is defined as the minimum number of check nodes in a Tanner graph T for C such that the size of the smallest stopping set in T is equal to the minimum distance of C. Han and Siegel recently proved an upper bound on the stopping redundancy of general linear codes, using probabilistic analysis. For most code parameters, this bound is the best currently...
It is now well known that the performance of a linear code Copf under iterative decoding on a binary erasure channel (and other channels) is determined by the size of the smallest stopping set in the Tanner graph for Copf. Several recent papers refer to this parameter as the stopping distance s of Copf. This is somewhat of a misnomer since the size of the smallest stopping set in the Tanner graph...
