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 "ldpc codes which can correct three errors under iterative decoding"):
  Abstract: In this paper, we provide necessary and sufficient conditions for a column-weight-three LDPC code to correct all patterns up to three errors when decoded using Gallager A algorithm. We then provide a construction technique which results in a code satisfying the above conditions. We also provide numerical assessment of code performance via simulation results.

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 "pseudo codeword analysis of tanner graphs from projective and euclidean planes":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "pseudocodeword free criterion for codes with cycle free tanner graph")
  Member "graph cover decoding and finite length analysis of message passing iterative decoding of ldpc codes":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "efficient qp admm decoder for binary ldpc codes and its performance analysis")
