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 5):
The apparatus of  claim 1  in which at least one of:\n (a) the storage device further stores instructions that when executed by the processor cause the processor to:\n estimate a particular linear phase offset associated with more than one component of a particular channel state information due to at least one of a sampling frequency offset (SFO) or a symbol timing offset (STO), \n estimate a particular initial phase offset associated with the more than one components of the particular channel state information due to at least one of a carrier frequency offset (CFO) or a common phase offset (CPO), and \n generate a particular corrected channel state information based on the particular channel state information, the estimated particular linear phase offset, and the estimated particular initial phase offset, \n \n (b) a linear phase offset associated with a channel state information is estimated based on component-wise product of the channel state information and a shifted version of the channel state information, or \n (c) an initial phase offset associated with a channel state information is estimated based on the angle of the average of the complex-valued channel state information components on each subcarrier.
