Abstract
The present invention provides a method, device, base station and subscriber unit for combining a plurality of antenna output signals to provide a combined data signal in a communication system where the antennas receive at least one user signal and where the at least one user signal contains pilot symbols and data symbols. The method includes the steps of: forming, in at least one communications receiver, a plurality of weighted antenna output signals, one for each antenna of a plurality of antennas, based on at least two covariance matrices and at least two steering vectors determined from the pilot symbols; and combining the weighted antenna output signals from the plurality of antennas to form the combined data signal.
