Noise subspace approach for interference cancellation
Jong‐Woo Kim, C.K. Un · Electronics Letters · 1989
We propose an interference cancelling method using the noise subspace of a covariance matrix in which the desired signal is subtracted. A beamformer using the method can generate deep nulls even for the interferences correlated with the desired signal or located dose to the look-direction. In addition, we consider how the method can be computed efficiently by utilising the minimum eigenvector.
