Abstract
Methods and apparatuses for WiFi CSI preprocessing for sensing applications are provided. A method of wireless communication performed by a STA comprises: receiving a sequence of frames; obtaining a CSI set, comprising the CSI for each of the frames; determining one or more variations in the CSI set caused by at least one of a device impairment, a synchronization issue, or an unintended signal; performing a preprocessing procedure configured to: correct one or more errors in gain and phase of each CSI of the CSI set caused by at least one of the device impairment or the synchronization issue, and filter at least one variation caused by the unintended signal; and identifying at least one of an outlier or a variation in CSI set that affects a sensing task, and performing at least one preprocessing operation configured to filter the outlier or the variation in CSI set.
