영문 초록

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 O(Mη) in an M-sensor array when η directional signals are present. The new method does not make any premises of the geometrical structure of arrays, and can be applied to arbitrary arrays.
