APPARATUS, SYSTEM, AND METHOD FOR RECOGNIZE EVENT ON THE BASIS OF WIRELESS SIGNAL

To recognize and classify an event in a palace on the basis of a wireless signal.SOLUTION: A first transmitter transmits a training wireless signal through a wireless multipath channel impacted by a known event in a venue in a training time period associated with the known event. A first receiver receives asynchronously the training wireless signal, and obtains, asynchronously time series of training channel information (CI) of the wireless multipath channel. A second transmitter transmits a current wireless signal through the wireless multipath channel impacted by a current event in a current time period. A second receiver receives asynchronously the current wireless signal, and obtains, asynchronously time series of current CI of the wireless multipath channel. An event recognition engine apples the classifier in order to: train a classifier on the basis of the training CI; classify the current CI; and associate the current event with at least one of: a known event, an unknown event, and another event.SELECTED DRAWING: None
