Abstract
A sensing recognition method and device based on wireless communication signals are disclosed. The method comprises the steps of obtaining channel state information from a received wireless communication signal; extracting a channel state feature value from the channel state information; and outputting a sensing result mapped with the channel state feature value according to the channel state feature value. The disclosed method and device can improve the accuracy of sensing recognition and achieve better recognition effect.
