Optimal energy and spectrum cooperative allocation is investigated for the downlink of two energy harvesting base stations in this paper. In particular, the joint maximization of the users' utilities and the base stations' revenues in two adjacent cells is considered. Each user can join either cell 1 or cell 2. When the users' choices on which cell to join are fixed, the energy and spectrum allocation...
In this paper, the interdigital structure is applied to the design of a miniaturized planar log-periodic antenna which is used in a TV broadcast wireless energy harvesting system. The lateral size of the printed antenna can be reduced approximately 35% while the overall performance characteristics is improved slightly. The simulated gain reaches 7.27dB at 515MHz and the measured −10-dB bandwidth is...
