1. A method of computing optimal combining coefficients for a plurality of received signals, comprising the steps of:

  • estimating an autocorrelation matrix for the plurality of signals based on received noise and interference associated with the plurality of signals;

    comparing the magnitudes of off-diagonal elements of the autocorrelation matrix with the magnitudes of diagonal elements of the autocorrelation matrix;

    setting the off-diagonal elements equal to zero if the magnitudes of the off-diagonal elements are significantly less than the magnitudes of the diagonal elements; and

    computing a plurality of optimal combining coefficients based on the autocorrelation matrix.
