Abstract

This paper deals with an eigenspace-based interference canceller under steering angle mismatch, correlated signals, and nonwhite noise. We construct a cost function consisting of two terms to be minimized. One represents the squared norm of the projection of the constraint vectors onto the noise subspace. The other one is related to the squared norm of the phase error vector due to steering angle error. An iterative algorithm is presented to solve the minimization problem. Simulations show the effectiveness of the proposed method.
