RIS-Enhanced WPCNs: Joint Radio Resource Allocation and Passive Beamforming Optimization
TL;DR: In this paper, a joint radio resource and passive beamforming optimization scheme for a downlink RIS-assisted wireless-powered communication network with a harvest-then-transmit protocol is proposed.
Journal ArticleDOI
Optimal Price-Based Power Control Algorithm in Cognitive Radio Networks
TL;DR: A novel algorithm is proposed to find the optimal price for the PU to maximize its revenue and shows the effectiveness of the proposed algorithm in comparison with the nonuniform pricing algorithm.
Journal ArticleDOI
A Novel Price-Based Power Control Algorithm in Cognitive Radio Networks
TL;DR: This letter proposes a novel price-based power control algorithm that improves the revenue of both the BS and SUs compared with the proportionate pricing algorithm and depicts the property of optimal transmit power of the SUs.
Journal ArticleDOI
Using a Single-DOF Test Vehicle to Simultaneously Retrieve the First Few Frequencies and Damping Ratios of the Bridge
TL;DR: The parametric study confirms that the contact response outperforms vehicle’s response in retrieving bridge frequencies and damping ratios, and the first few frequencies can be identified with robustness for reasonable levels of road roughness, vehicle speed, bridge damping and noise.
Journal ArticleDOI
Damped test vehicle for scanning bridge frequencies: Theory, simulation and experiment
TL;DR: In this paper, a realistic theory is proposed considering the damping effect of the test vehicle, which was not well studied previously, and closed-form solutions are firstly derived for both the vehicle and contact point responses, with their transmissibility discussed.
