Computationally Efficient Adaptive Beamforming Method Based on Interference Subspace Extraction
간섭 부공간 추출에 기초한 계산이 간단한 적응 빔 형성 기법
Abstract
This paper addresses a computationally simple adaptive beamforming method to cancel interferences arriving onto a sensor array. In the proposed method, an estimate of the interference subspace is extracted from a submatrix of the sample covariance matrix and an orthonormal basis for the estimated subspace is efficiently found, one basis vector being updated every sample. Its computational burden is just
