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 "any positive feedback rate increases the capacity of strictly less noisy broadcast channels"):
  Abstract: We propose two coding schemes for discrete memoryless broadcast channels (DMBCs) with rate-limited feedback from only one receiver. For any positive feedback rate and for the class of strictly less-noisy DMBCs, our schemes strictly improve over the no-feedback capacity region.

Includes members:
  Member "an achievable rate region for the broadcast channel with feedback":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "exploiting location information to enhance throughput in downlink v2i systems")
  Member "lqg control approach to gaussian broadcast channels with feedback":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "youla coding and computation of gaussian feedback capacity")
  Member "feedback can double the prelog of some memoryless gaussian networks":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "insufficiency of linear feedback schemes in gaussian broadcast channels with common message")
  Member "on the capacity of the discrete memoryless broadcast channel with feedback":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "exploiting location information to enhance throughput in downlink v2i systems")
