Claim One:
1. A method of processing a received information signal transmitted from at least primary and secondary transmit antennas, the method comprising: receiving a spread-spectrum information signal transmitted from at least primary and secondary transmit antennas, the secondary antenna transmitting the signal using one of a plurality of known antenna weights relative to the primary antenna; computing impairment or data covariance terms corresponding to the plurality of known, relative antenna weights of the secondary antenna; measuring an impairment or data covariance associated with the received information signal; jointly estimating values of fitting parameters in response to the measured impairment or data covariance and the computed impairment or data covariance terms; and estimating a received signal impairment or data covariance for the received information signal by applying the estimated values of the fitting parameters to the impairment or data covariance terms.
