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 "partially overlapping tones for uncoordinated networks"):
  Abstract: In an uncoordinated network, the link-level performance of a wireless receiver might degrade significantly due to the interference from other transmitters that share the same spectrum. As a solution, in this study, the concept of partially overlapping tones (POT) is introduced. In POT, interference energy observed at a victim receiver is mitigated by partially overlapping the individual subcarriers via an intentional carrier frequency offset between the links. It is argued that the self-interference arising due to the use of POT can be more easily addressed than the dominant other-user interference, potentially yielding higher spectral efficiencies with POT. Using a spatial Poisson point process based framework, a tractable bit error rate analysis is provided to demonstrate potential benefits emerging from POT in system-level scenarios.
