Rapid interference suppression using Kalman filter approach
Abstract
Directional interference suppression is based upon a recursive estimation procedure of the state of a filter generating the angular interference spectrum. This leads to an iterative solution of the Wiener-Hopf matrix equation. Simulation results compare the convergence rate of the proposed technique and the gradient method.
