Abstract: A method disclosed in the present invention utilizes an image captured by an image capture device to assist physiological signal paring. Multiple vital signs in the physiological signal detected by a radar are able to be paired with multiple subjects in the image one on one accurately to realize continuous tracking of vital signs of multiple subjects.

Abstract: The beamforming calibration system includes a transmitter, a receiver, and a computing device. The transmitter includes multiple transmitting antennas. The computing device provides multiple phase sets to the transmitter. When the computing device provides a first phase set among the phase sets to the transmitter: the transmitter uses the first phase set to set phases of the transmitting antennas, the receiver receives wireless transmission signal from the transmitting antennas to obtain a first radiation pattern corresponding to the first phase set, and the computing device is configured to compare the first radiation pattern with a predetermined pattern to calculate a pattern similarity score corresponding to the first phase set. The computing device selects a calibration phase set among the phase sets according to the pattern similarity score of each phase set, and provides the calibration phase set to the transmitter to calibrate beamforming.

Abstract: The disclosure is directed to an OFDM receiver with a low-resolution ADC and an electronic device thereof. According to one of the exemplary embodiments, the OFDM receiver may include not limited to: an ADC module which receives a transmission signal of a channel in an analog format and digitizes the transmission signal into a digital format to generate a quantized transmission signal; an error compensating and estimating module which is coupled to the ADC module, receives the quantized transmission signal and a feedback signal which is a first estimated time-domain transmission signal to generate an estimated error signal according to a turbo iterative updating technique; and a signal estimating module which is coupled to the error compensating and estimating module, receives the estimated error signal and a channel attenuation coefficient of the channel to generate an estimated transmission signal.

Abstract: The present disclosure discloses a receiver device, including receiving antennas, radio frequency receivers, a configurable precision analog-to-digital converter, a switch device, a baseband processor, and an analog-to-digital controller. The switch device converts a first number of baseband analog signals into a second number of baseband analog signals. The configurable precision analog-to-digital converter converts the second number of baseband analog signals into a third number of first baseband digital signals. The configurable precision analog-to-digital converter combines at least two of first analog-to-digital converters into at least one second analog-to-digital converter so that the total number of the rest of the first analog-to-digital converters and the at least one second analog-to-digital converters is equal to the third number. The resolution of each of the second analog-to-digital converters is higher than the resolution of each of the first analog-to-digital converters.
