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 "two bit message passing decoders for ldpc codes over the binary symmetric channel"):
  Abstract: A class of two-bit message passing decoders for decoding column-weight-four LDPC codes over the binary symmetric channel is proposed. The thresholds for various decoders in this class are derived using density evolution. For a specific decoder, the sufficient conditions for correcting all error patterns with up to three errors are derived.

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 "low density parity check codes which can correct three errors under iterative decoding":
    also connected through other hyperedges:
      (none)
  Member "ldpc codes which can correct three errors under iterative decoding":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "finite alphabet iterative decoders part ii towards guaranteed error correction of ldpc codes via iterative decoder diversity")
  Member "error correction capability of column weight three ldpc codes":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "thresholds of absorbing sets in low density parity check codes")
