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: "on the performance of reduced complexity transmit receive diversity systems over mimo v2v channel model"
  Abstract: In this letter, we investigate the performance of multiple-input multiple-output techniques in a vehicle-to-vehicle communication system. We consider both transmit antenna selection with maximal-ratio combining and transmit antenna selection with selection combining. The channel propagation model between two vehicles is represented as    ${n}$   *Rayleigh distribution, which has been shown to be a realistic model for vehicle-to-vehicle communication scenarios. We derive tight analytical expressions for the outage probability and amount of fading of the post-processing signal-to-noise ratio.

Connected through hyperedge HE-1 (induced by source paper "improved s af and s df relaying schemes using machine learning based power allocation over cascaded rayleigh fading channels"):
  with members:
    - "on the performance of multihop intervehicular communications systems over n rayleigh fading channels"
    - "on the approximate analysis of energy detection over n ast rayleigh fading channels through cooperative spectrum sensing"
