Abstract: Provided are a spatial filtering apparatus for selecting target terminals within a certain distance among a plurality of targets by using transit delay time difference between a radio signal and a sonic signal and a method thereof. A user terminal transmits a sonic signal to adjacent terminals to select a terminal located at a certain distance from the user terminal among the adjacent terminals and transmits radio signal to the adjacent terminals after a predetermined transit delay time has passed. The user terminal receives a response signal from adjacent terminals of which the difference to the user terminal is within the predetermined range among the multiple adjacent terminals receiving a radio signal and a sonic signal. The adjacent terminal receives the sonic signal from the user terminal and receives the transmitted radio signal after the predetermined transit delay from the user terminal using a distance to the target terminal. User terminal is determined if it is the target terminal by using receiving time difference of the radio signal and sonic signal from the user terminal to adjacent terminals. And if the determination information is confirmed to be in the predetermined range, the response signal is transmitted to the user terminal.

Abstract: Disclosed are a spatial filtering apparatus and method using a transmission delay time difference of a signal. An apparatus for receiving a response from a receiver through spatial filtering includes: a first signal generator for generating a first signal; a second signal generator for generating a second signal, which is spaced apart from the first signal generator at a predetermined distance; and a response receiving unit for receiving a response based on the difference in receiving time between the first and second signals from the receiving apparatus. The first and second signals are transmitted at a predetermined interval by taking into consideration of the direction of the receiver to be detected so that the apparatus can perform the spatial filtering for the receiver located in a required direction.

Abstract: PURPOSE: A terminal for recognizing a communication target in a visible range and a method thereof are provided to select the communication target through intuitive procedures and form a communication link with the selected communication target. CONSTITUTION: A terminal (1) includes a sensor (11), a communication unit (12), a control unit, and an output unit (14). The sensor obtains the direction information including a direction and an azimuth of the terminal. The communication unit receives the position information by requesting the position information from a communication target which does not know about the identifier information in a visible range of a terminal user. The control unit grasps a relative position of the communication target by using the position information of the communication target and the direction information of a terminal and maps the grasped relative position of the communication target on a screen of the terminal. The output unit displays the relative position of the communication target mapped through the control unit on the screen.
