human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "on the guaranteed error correction capability of ldpc codes"):
  Abstract: We investigate the relation between the girth and the guaranteed error correction capability of gamma-left regular LDPC codes when decoded using the bit flipping (serial and parallel) algorithms. A lower bound on the number of variable nodes which expand by a factor of at least 3gamma/4 is found based on the Moore bound. An upper bound on the guaranteed correction capability is established by studying the sizes of smallest possible trapping sets.

Includes members:
  Member "error correction capability of column weight three ldpc codes":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "thresholds of absorbing sets in low density parity check codes")
  Member "error correction capability of column weight three ldpc codes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "thresholds of absorbing sets in low density parity check codes")
  Member "graph cover decoding and finite length analysis of message passing iterative decoding of ldpc codes":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "efficient qp admm decoder for binary ldpc codes and its performance analysis")
