Title:
BROADBAND MULTI-USER WIRELESS POWER TRANSFER WAVEFORM DESIGN CONSIDERING NONLINEAR ENERGY HARVESTER
Document Type and Number:
WIPO Patent Application WO/2023/027270
Kind Code:
A1
Abstract:
Proposed are a broadband multi-user wireless power transfer method and apparatus considering a nonlinear energy harvester, and the wireless power transfer method in a multi-path channel proposed by the present invention comprises the steps of: arranging, in a reverse order of time, channels of a plurality of receivers for receiving time reversal (TR) waveforms transmitted from a transmitter; generating TR waveforms by using the channels of the plurality of receivers, which are arranged in the reverse order of time; and generating, by the transmitter, phase aligned time reversal (PATR) waveforms by aligning, in phase, phase differences between components of the TR waveforms to be received by each receiver receiving the TR waveforms from the transmitter.
