Claim One:
1. A method of mitigating interference for received signals in a communication system, characterized by the steps of: receiving a transmitted signal via at least two antenna elements; estimating a channel for said received signals; estimating a disturbance covariance matrix based on said channel estimate, said estimated disturbance covariance matrix representing received interference plus noise of said received signals; adapting said estimated covariance matrix by enhancing the diagonal elements of said covariance matrix to provide an enhanced covariance matrix, to reduce the spread in the eigenvalues of said covariance matrix, and thereby improve the robustness of the covariance matrix; selectively using IRC and/or MRC to mitigate interference of said received signal, based on at least said channel estimate and on said enhanced covariance matrix, to provide a received signal with improved quality on channels with Doppler frequency.
