Abstract

The embodiment of the invention discloses a target state determination method and device, an electronic device and a readable storage medium. The method comprises: acquiring channel state informationof each channel in N channels; wherein N is an integer greater than 1; performing offset elimination processing on the channel state information of each channel to obtain aggregated channel state information, and the aggregated channel state information comprising the channel state information of each channel after offset elimination processing; acquiring characteristics of the aggregated channelstate information; and determining a target state corresponding to the aggregated channel state according to the characteristics of the aggregated channel state information. According to the technicalscheme, the channel bandwidth can be expanded, so that the target state can be sensed more finely.

Description

Technical field [0001] The present disclosure relates to the field of wireless sensing technology, and in particular to a method, device, electronic device, and readable storage medium for determining a target state. Background technique [0002] Currently, wireless sensing technology can be used to perceive the target state in the space. The principle is that in a space, the transmitting end may transmit wireless signals to the receiving end through multiple propagation paths, and the target activity or static state in this space can affect the propagation path of the wireless signal, and then the wireless signal can pass through The difference between different propagation paths transmitted to the receiving end determines the target state in the space. [0003] A specific way of realizing wireless sensing technology is: the receiving end receives wireless signals from the channel used to receive wireless signals, and obtains channel state information (CSI) according to the recei...
