An Adaptive Escalator Beamformer with Linear Constraints
선형 제한 조건을 갖는 적응 Escalator 빔 형성기
Abstract
As a method of separating the signal arriving from a desired direction in the presence of noise and interfering signals, a linearly constrained adaptive beamformer based on the escalator (Gram-Schmidt) structure is presented. The weights are chosen to minimize local output power subject to the response constraint. The performances of the proposed escalator adaptive beamformer are compared with those of cascade adaptive beamformer via computer simulations.
