Abstract
The present invention relates to beamforming in a multi-carrier multi-user communication system applying an adaptive method for determining transmit weights for the various antenna beams. A set of complex transmission weights is adapted in response to appropriate feedback information on transmission quality from receiving units in order to achieve a maximization of a function of said quality indicator and thus optimize the transmission of the pilot signal.
