The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Optimal Resource Allocation for MIMO Ad Hoc Cognitive Radio Networks (2008, methodology): “Here, we specifically adopt the spectrum underlay architecture, where the interference power at the PU is regulated [34].”
Ten years of research in spectrum sensing and sharing in cognitive radio (2012, neutral): “Under IPCs and peak TPCs, the power allocation and beamforming design for sum-rate maximization and signal-to-interference-plus-noise ratios (SINRs) balancing problems have been studied for SIMO systems in [92].”
Optimal power allocation for fading channels in cognitive radio networks: Ergodic capacity and outage capacity (2008, background): “for multi-antenna CR transmitters, and in [12] for multiple CR transmitters in a multiple-access channel (MAC).”
Max-Min SINR Coordinated Multipoint Downlink Transmission—Duality and Algorithms (2012, methodology): “Moreover, the proof in [20] that shows one can decouple multiple power constraints into subproblems each involving one power constraint relies on induction, which does not give insight into the problem structure.”
