Abstract: A new blind beamforming algorithm to fast track several movable users was proposed in this paper. Instead of forming independent beams at different times by the conventional method, the information of the users' DOA obtained from the previous beamforming is made full use of.It can greatly speed up the subsequent beamforming and lead to enormous saving in the required real time computations.Therefore, the new beamforming algorithm could keep up with the moving targets more quickly, which is of great importance in real communication systems.Simulation results confirm our ideas.

Key words: blind adaptive beamforming, direction-of-arrival, adaptive beamforming
