Abstract

The invention belongs to the technical field of wireless energy transmission, and provides a controllable intelligent surface auxiliary energy transmission device and a transmission method thereof. Firstly, all the receiving terminals transmit orthogonal pilot signals, and each controllable intelligent surface estimates channel information from all the receiving terminals to the controllable intelligent surface; all the controllable intelligent surfaces send orthogonal pilot signals, and the energy station can estimate channels from all the controllable intelligent surfaces to each antenna ofthe energy station; secondly, all the controllable intelligent surfaces and the energy station exchange large-scale channel information, and the controllable intelligent surfaces calculate required phase angles and precoding coefficients required by the energy station by using the estimated channel information; and finally, the energy station radiates signals to the controllable intelligent surface by using the constructed precoding, and all receiving terminals collect energy. According to the invention, the controllable intelligent surfaces are used to change the transmission path of the signal, and energy transmission of the user is shielded.

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission, and relates to a controllable smart surface auxiliary energy transmission device and a transmission method thereof. Background technique [0002] At present, the application of wireless energy transmission technology based on radio frequency is limited. On the one hand, due to the complex space propagation environment, when there is an impact such as object occlusion, the signal energy received by the terminal is low; on the other hand, how to use high-gain controllable intelligence The effect of improving energy transmission also needs to be further studied. First of all, how to carry out the precoding design of the transmitter and the phase regulation of the controllable intelligent surface to improve the energy transmission effect is worthy of in-depth study; secondly, how to jointly apply multiple controllable intelligent surfaces to cooperatively control the phase of the...
