摘要：
Methods, apparatus and systems for wireless vital signs monitoring are described. In one embodiment, a described system comprises: a transmitter, a receiver, a processor. The transmitter transmits, using N1 transmit antennas, a wireless signal through a wireless multipath channel of a venue, while a first object in the venue is having a first repetitive motion. The receiver receives, using N2 receive antennas, the wireless signal through the wireless multipath channel, and extracts a plurality of time series of channel information (TSCI) of the wireless multipath channel from the wireless signal. N1 and N2 are positive integers. Each of the plurality of TSCI is associated with a transmit antenna of the transmitter and a receive antenna of the receiver. The processor computes a first information of the first repetitive motion based on the plurality of TSCI, and monitors the first repetitive motion of the first object based on the first information.
