The method may include receiving a primary pilot channel and a secondary pilot channel, deriving two or more composite channels from the received primary and secondary pilot channels, deriving two or more physical channels from the derived two or more composite channels, and synthesizing a composite channel estimate for a dominant virtual antenna from the two or more derived physical channels and a beamforming weight vector.
