RADIO-FREQUENCY ENERGY COLLECTION SYSTEM AND METHOD USING BLIND ADAPTIVE BEAMFORMING ALGORITHM

摘要

Provided are a radio-frequency energy collection system and method using a blind adaptive beamforming algorithm, relating to the technical field of wireless energy transmission. The system comprises a transmitting end and an energy receiver, wherein the transmitting end emits a radio frequency signal and the energy receiver receives the radio frequency signal emitted by the transmitting end; the transmitting end comprises N transmitting end modules and N is an positive integer; each transmitting end module comprises an MCU and a radio frequency front-end; and each radio frequency front-end is connected to a transmitting antenna. The method generates the best beamforming parameter by means of loop iteration. The system and the method avoid complex computation in channel estimation.
