Abstract: A computing system includes a storage device and processing circuitry having access to the storage device. The processing circuitry is configured to receive a sequence of channel state information (CSI) samples, and calculate, based on the sequence of CSI samples, frequency domain information including a set of frequency domain values for each frequency band of a plurality of frequency bands. The processing circuitry is further configured to select a set of frequency bands of the plurality of frequency bands; and calculate, based on the set of frequency domain values for each frequency band of the set of frequency bands, a set of similarity values. Additionally, the processing circuitry is configured to determine, based on the set of similarity values, information indicative of one or more characteristics of a space between a first computing device and a second computing device, and perform an action based on the information.
