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 "a complementary construction using mutually unbiased bases"):
  Abstract: We present a construction for complementary pairs of arrays that exploits a set of mutually-unbiased bases, and enumerate these arrays as well as the corresponding set of complementary sequences obtained from the arrays by projection. We also sketch an algorithm to uniquely generate these sequences. The pairwise squared inner-product of members of the sequence set is shown to be $\frac{1}{2}$. Moreover, a subset of the set can be viewed as a codebook that asymptotically achieves $\sqrt{\frac{3}{2}}$ times the Welch bound.

Includes members:
  Member "complementary sets generalized reed muller codes and power control for ofdm":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "new constructions of cross z complementary pairs")
  Member "on cosets of the generalized first order reed muller code with low pmepr":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "low pmepr preamble sequence design for dynamic spectrum allocation in ofdma systems")
