Claim 0:
1. A display device comprising:
a communicator comprising communication circuitry configured to receive a wireless signal transmitted by a wireless router;
a memory configured to store one or more instructions; and
a processor configured to execute the one or more instructions stored in the memory,
wherein the processor is configured to:
continuously retrieve multipath channel characteristic data based on the wireless signal,
perform preprocessing on the retrieved multipath channel characteristic data of the wireless signal,
determine representative values for each reference time by calculating a similarity for each time period of result data corresponding to a result of the preprocessing,
determine a motion within a specified region of the display device, based on a change in the representative values over time, and
control the display device based on the determined motion within the specified region of the display device,
wherein the performing of the preprocessing comprises:
detecting a data gap in a first frequency band of multipath measurement characteristic data, and
removing the data gap by replacing the data gap with an amplitude value of a second frequency band adjacent to the first frequency band.
