Center hyperedge (induced by source paper "a new interweave cognitive radio scheme for out band energy harvesting systems"):
  Abstract: In this paper, a new interweave cognitive radio (CR) transmission scheme is analytically presented for energy harvesting (EH)-enabled transmitting nodes. EH is performed via a dedicated power beacon (PB) base station through wireless power transfer, which harvests energy to both primary and secondary systems. The out-band mode-of-operation between PB and the two heterogeneous systems is considered (i.e., data communication and EH are realized at different frequency bands). The performance of the new interweave CR system is studied under independent and not necessarily identically distributed $\kappa-\mu$ shadowed faded channels. Representative numerical and simulation results corroborate the effectiveness of the proposed scheme and presented analysis, while some useful engineering insights are provided.
