Abstract
A method of measuring a direction between devices performing ultra-wide band (UWB) communication and each including a plurality of antennas includes transmitting signals through a plurality of antennas by a transmitting device and receiving the signals through a plurality of antennas by a receiving device, and selecting at least one of an angle of departure (AoD) method and an angle of arrival (AoA) method depending on statuses of the transmitting device and the receiving device and measuring the direction between the devices by using a selected method.
Claims15
A method of measuring a direction between devices performing ultra-wide band (UWB) communication and each including a plurality of antennas, the method comprising:
- transmitting signals through a plurality of antennas by a transmitting device and receiving the signals through a plurality of antennas by a receiving device;
- and
- selecting at least one of an angle of departure (AoD) method and an angle of arrival (AoA) method based on a result of comparing a size of an AoD and a size of an AoA measured by the receiving device, or based on which one of the receiving device and the transmitting device moves, and measuring the direction between the devices by using a selected method,
- wherein the AoD method is a method of measuring the AoD of signals transmitted through two or more different antennas from the transmitting device based on a phase difference between the transmitted signals, and the AoA method is a method of measuring the AoA of signals received through two or more different antennas by the receiving device based on a phase difference between the received signals.
A receiving device for performing direction finding based on ultra-wide band (UWB), the receiving device comprising:
- an antenna module including a plurality of antennas arranged at half-wavelength intervals of a received signal;
- a memory configured to store a program therein for performing direction finding;
- and
- at least one processor,
- wherein the processor is configured to
- receive signals transmitted through a plurality of antennas from the transmitting device,
- select at least one of an angle of departure (AoD) method and an angle of arrival (AoA) method based on a result of comparing a size of an AoD and a size of an AoA measured by the receiving device, or based on which one of the receiving device and the transmitting device moves, and measure the direction between the devices by using a selected method, and
- the AoD method is a method of measuring the AoD of signals transmitted through two or more antennas from the transmitting device based on a phase difference between the transmitted signals and the AoA method is a method of measuring the AoA of signals received through two or more different antennas by the receiving device based on a phase difference between the received signals.
