- W3145936306 abstract "본 연구는 무선통신에서 선형 배열 안테나를 이용하여 원하는 목표물의 도래 방향을 추정 한다. 도래방향 추정은 수신기 배열 안테나에 입사하는 신호들 중에서 원하는 신호를 추정하는 것이다. 본 연구에서는 도래방향 추정을 위한 최적 가중치와 고 분해능 적응 빔 형성 알고리즘과 회소행렬을 사용하여 목표물에 대한 도래방향을 추정 정확도를 향상 시켰다. 모의실험을 통하여 목표물 도래 방향 추정에서 기존의 적응 빔 형성 알고리즘과 제안 알고리즘의 성능을 비교 분석 하였다. 목표물 도래 방향 추정에서 제안한 알고리즘이 기존의 빔형성 알고리즘보다 도래 방향추정 능력이 향상되었다. In this paper, we estimates the direction of arrival of desired a target using linear array antenna in wireless communication. Direction of arrival estimation is to estimate for desired target position among incident signals on receiver array antennas. This paper improved estimation of direction of arrival for target using optimum weight, high resolution adaptive beamforming algorithm, and sparse matrix for driection of arrival estimation. Through simulation, we showed that we are performance the analysis to compare general algorithm with proposed algorithm. We show that propose algorithm more improve for direction of estimation than general beamforming algorithm." @default.
