Abstract:
A wireless power reception apparatus includes a reception (RX) resonator configured to form a resonance coupling with a first resonance period associated with an envelope of a power to receive the power from a transmission (TX) resonator; a switch controller configured to generate, at intervals of the first resonance period, a control signal to deactivate the RX resonator at an off timing corresponding to a time instant at which a maximum energy is stored in an inductor of the RX resonator; and a switch configured to deactivate the RX resonator in response to the control signal.
Abstract:
An apparatus and a method for processing a signal, and for estimating a point corresponding to a maximum slope from an envelope of an input signal, are provided. A signal processing apparatus includes an envelope detecting unit configured to detect an envelope of an input signal. The signal processing apparatus further includes a correcting unit configured to correct slopes, each of the slopes being between respective points of the envelope, based on information on a clipping interval of the envelope. The signal processing apparatus further includes an estimating unit configured to estimate a point, of the envelope, in which a corrected slope, among the corrected slopes, includes a maximum value.
