human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "a generalized construction of ofdm m qam sequences with low peak to average power ratio"
  Abstract: A construction of $2^{2n}$-QAM sequences is given and an upper bound of the peak-to-mean envelope power ratio (PMEPR) is determined. Some former works can be viewed as special cases of this construction.

Connected through hyperedge HE-1 (induced by source paper "new construction of complementary sequence or array sets and complete complementary codes"):
  with members:
    - "a radix m construction for complementary sets"
    - "complementary lattice arrays for coded aperture imaging"
    - "new constructions of zero correlation zone sequences"
    - "complementary sets generalized reed muller codes and power control for ofdm"
    - "on cosets of the generalized first order reed muller code with low pmepr"

Connected through hyperedge HE-2 (induced by source paper "a new method to construct gloay complementary set by paraunitary matrices and hadamard matrices"):
  with members:
    - "complementary sets generalized reed muller codes and power control for ofdm"
    - "on cosets of the generalized first order reed muller code with low pmepr"
