摘要： A transceiver may include a reception (Rx) radio frequency (RF) part configured to process a received signal, a transmission (Tx) RF part configured to process a transmitted signal, and a phase lock loop (PLL) configured to provide a reception frequency to the reception RF part and provide a transmission frequency to the transmission RF part. The PLL may be controlled according to whether the reception RF part or the transmission RF part is on. In addition, a transceiver may include quenching waveform generator (QWGs) to control quenching waveforms of the RF parts corresponding to a plurality of antennas. The quenching waveforms may be generated respectively by VCOs operating at a same frequency. The QWGs may control the VCOs such that the quenching waveforms do not overlap.

摘要： A wireless power transmitter includes a signal generator for generating power signals, a modulator for modulating a phase of a power signal to be time reversed based on beacon signals received from the wireless power transmitter and modulating an amplitude of a power signal to be amplified, a controller for providing a phase and amplitude control algorithm to be performed by the modulator, and an antenna unit for transmitting the power signals and receiving the beacon signals. The wireless power transmitter controls the amplification of amplitudes by using the phase and amplitude control algorithm, thereby improving wireless power transmission efficiency. In addition, the wireless power transmitter includes a multiple polarization antenna to enable high-efficiency wireless power transmission, regardless of a direction of the power signals and a direction of polarization.

摘要： A distance measuring method and apparatus are provided. The distance measuring apparatus emits a transmission signal while changing a frequency over time, receives a reception signal from an object in response to the transmission signal being reflected from the object, samples a beat frequency indicating a difference between a frequency of the transmission signal and a frequency of the reception signal in a sampling range that changes based on the beat frequency, and determines a distance to the object based on the sampling.
