摘要
This paper considers wireless power transfer with feedback-based distributed transmit beamforming in a narrowband setting where all nodes have independent local oscillators with stochastic dynamics. The receive node provides periodic feedback to the transmit nodes to facilitate efficient wireless power transfer. The optimal feedback rate to maximize the amount of energy harvested by the receive node per unit of time is analyzed and a method to numerically calculate the optimal feedback rate is provided. The results demonstrate that the efficiency of wireless power transfer can be significantly improved with feedback-based distributed transmit beamforming and feedback rate optimization.
