A new adaptive LCMV solution that avoids DOA estimation for uplink beamforming is proposed.The use of the uplink channel covariance matrix (UCCM) instead of DOA estimation is shown to be a suitable alternative for constraints selection.The resulting LCMV adaptive solutions are then based on the LMS and RLS versions with the UCCM estimation.The new method is then evaluated for packed-like wireless systems through computational simulations.
