도달각을 알 수 없는 일관성 있는 신호를 처리하기 위해 임의 배열에 적용할 수 있는 적응형 빔형성 방법이 제안됩니다. 제안된 방법은 교번 최대화와 함께 브렌트 방법을 활용하여 원하는 일관성 있는 신호 그룹의 도달 각도를 추정하기 위해 일반화된 고유치 문제를 효율적으로 해결합니다. 우리는 원하는 간섭 방향 추정을 잘못하지 않고 올바른 방향 추정을 위한 조건을 논의합니다. 시뮬레이션 결과는 제안된 빔포머의 성능이 정확한 복합 스티어링 벡터(CSV)를 갖는 빔포머의 성능과 매우 유사하다는 것을 보여줍니다.

Abstract: To handle coherent signals with unknown arrival angles, an adaptive beamforming method is proposed which can be applied to an arbitrary array. The proposed method efficiently solves a generalized eigenvalue problem to estimate the arrival angles of the desired coherent signal group, by exploiting the Brent method in conjunction with alternating maximization. We discuss the condition for the correct direction estimation without erroneously taking interference direction estimates for the desired ones. Simulation results show that the performance of the proposed beamformer is very similar to that of the beamformer with the exact composite steering vector (CSV).
