Abstract:
An apparatus for detecting events includes a processor and a storage device storing instructions that when executed by the processor cause the processor to train a classifier for classifying channel state information (CSI) and detecting an event based on the classification of the CSI obtained during a monitoring phase. The training of the classifier includes: for each of the known events to be detected, during a time period in which the known event occurs in a venue, obtain training CSI of a wireless multipath channel between a wireless transmitter and a wireless receiver in the venue, in which the training CSI is derived from one or more probing signals sent from the transmitter through the wireless multipath channel to the receiver, and train the classifier based on the known events and the training CSI associated with each of the events.

Claim (Index 24):
The apparatus of  claim 1  in which at least one of:\n (a) training the at least one classifier comprises:\n compensating phase offsets in the sets of training channel state information associated with each known event prior to identifying a representative set of training channel state information associated with the known event; \n estimating location and scale parameters of a parameter representing (1\u2212TR) or TR associated with the known event in which TR represents intra-class time-reversal resonating strength parameter values computed based on the representative set of training channel state information associated with the known event and \n establishing a training database that includes information about, for each link between a transmitter antenna and a receiver antenna, for each known event to be detected, the location and scale parameters of the parameter representing (1\u2212TR) or TR, and the representative set of channel state information associated with the known event and the link; or \n \n (b) applying the classifier to at least one of the set of measured channel state information or data derived from the set of measured channel state information comprises:\n compensating a phase offset, if any, of each set of measured channel state information, \n for each link between each transmitter antenna and each receiver antenna, for each known event, \n computing a second set of intra-class time-reversal resonating strength parameter values, each of the intra-class time-reversal resonating strength parameter values being computed based on the set of measured channel state information and a representative set of channel state information associated with the link and the known event, and \n determining which of the known events matches the current event based on information derived from the second set of intra-class time-reversal resonating strength parameter values.
