Abstract
An apparatus and method for collecting the radio frequency (RF) feature of a wireless device in a wireless communication apparatus are disclosed herein. The RF feature extraction unit adds a tag having a unique value to a received radio signal, and extracts RF feature information from the radio signal. The MAC information extraction unit extracts the source MAC address and tag information of a MAC protocol frame from the received radio signal, and then removes the added tag. The tag comparison unit selects an source MAC address and RF feature information, when the tags have the same value, from the RF feature information and tag information from the RF feature extraction unit and the source MAC address and tag information from the MAC information extraction unit. The RF feature storage unit stores the selected source MAC address and RF feature information.
