Center node: "average stopping set weight distribution of redundant random matrix ensembles"
  Abstract: In this paper, redundant random matrix ensembles (abbreviated as redundant random ensembles) are defined and their stopping set (SS) weight distributions are analyzed. A redundant random ensemble consists of a set of binary matrices with linearly dependent rows. These linearly dependent rows (redundant rows) significantly reduce the number of stopping sets of small size. Upper and lower bounds on the average SS weight distribution of the redundant random ensembles are shown.

Connected through hyperedge HE-1 (induced by source paper "permutation decoding and the stopping redundancy hierarchy of cyclic and extended cyclic codes"):
  with members:
    - "on parity check collections for iterative erasure decoding that correct all correctable erasure patterns of a given size"
    - "on the hardness of approximating stopping and trapping sets in ldpc codes"
    - "complete enumeration of stopping sets of full rank parity check matrices of hamming codes"
    - "on the stopping distance and the stopping redundancy of codes"
    - "improved upper bounds on stopping redundancy"
