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 "capacity of generalized discrete memoryless push to talk two way channels"):
  Abstract: In this report, we generalize Shannon's push-to-talk two-way channel (PTT-TWC) by allowing reliable full-duplex transmission as well as noisy reception in the half-duplex (PTT) mode. Viewing a PTT-TWC as two state-dependent one-way channels, we introduce a channel symmetry property pertaining to the one-way channels. Shannon's TWC capacity inner bound is shown to be tight for the generalized model under this symmetry property. We also analytically derive the capacity region, which is shown to be the convex hull of (at most) 4 rate pairs. Examples that illustrate different shapes of the capacity region are given, and efficient transmission schemes are discussed via the examples.

Includes members:
  Member "lossy transmission of correlated sources over two way channels":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "adaptive coding for two way lossy source channel communication")
  Member "adaptation is useless for two discrete additive noise two way channels":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "joint source channel coding for the transmission of correlated sources over two way channels")
  Member "two way networks when adaptation is useless":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "classes of full duplex channels with capacity achieved without adaptation")
