Abstract
Methods, apparatus and systems for wirelessly monitoring a micro motion of an object are described. In one example, a described system comprises: a transmitter configured for transmitting a first wireless signal through a wireless multipath channel of a venue; a receiver configured for receiving a second wireless signal through the wireless multipath channel; and a processor. The second wireless signal differs from the first wireless signal due to the wireless multipath channel and a motion of an object in the venue. The processor is configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal, wherein each channel information (CI) of the TSCI comprises N1 CI components; selecting N2 CI components from the N1 CI components based on a first analysis of the N1 CI components; computing a micro-motion (MM) statistics based on the N2 selected CI components and the first analysis; monitoring the motion of the object based on a second analysis of the MM statistics; performing a task based on the first analysis and the second analysis; and generating a response based on the task, the first analysis and the second analysis.
