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 22):
The apparatus of  claim 1  in which at least one of:\n (a) the at least one classifier comprises a statistics based classifier, and training the at least one classifier comprises:\n for each link between each transmitter antenna and each receiver antenna,\n receiving a plurality of sets of training channel state information associated with a particular known event, and \n identifying a representative set of training channel state information that is representative of the plurality of sets of training channel state information associated with the particular known event; and \n \n training the at least one classifier using the representative sets of training channel state information, or \n \n (b) training the at least one classifier comprises:\n computing a plurality of intra-class time-reversal resonating strength parameter values, each of the intra-class time-reversal resonating strength parameter values being computed based on a representative set of channel state information associated with a particular known event and the other sets of channel state information associated with the particular known event, and \n training the at least one classifier based on the plurality of intra-class time-reversal resonating strength parameter values.
