Zusammenfassung:	A system of estimating an angle of arrival and method of estimating an angle of arrival may be disclosed. A system of estimating an angle of arrival according to an embodiment may include: a plurality of antennas for receiving signals and generating received signals; a switch type circuit module that is connected to the plurality of antennas, selects a mode representing a combination of reception paths of the plurality of antennas, and generates an I signal (in-phase signal) and a Q signal (quadrature signal) corresponding to the mode based on a received signal that passes or crosses according to the mode; and an angle of arrival estimation part for estimating an angle of arrival based on the I signal and the Q signal. 도래각 추정 시스템 및 도래각 추정 방법이 개시될 수 있다. 일 실시예에 따른 도래각 추정 시스템은 신호를 수신하여 수신 신호를 생성하는 복수의 안테나; 복수의 안테나에 연결되고, 복수의 안테나의 수신 경로 조합을 나타내는 모드를 선택하고, 모드에 따라 통과 또는 교차하는 수신 신호에 기초하여 모드에 대응하는 I 신호(in-phase signal) 및 Q 신호(quadrature signal)를 생성하는 스위치형 회로 모듈; 및 I 신호 및 Q 신호에 기초하여 도래각을 추정하는 도래각 추정부를 포함할 수 있다.
