This paper presented the possibility of performance improvement of blind adaptive beamforming algorithms using a new proposed pre-filtering technique. We will introduce the idea of this technique with the necessary mathematical derivation. Simulation results of this technique show that there is a significant improvement in beam pattern characteristics with increasing in Signal-to-Interference Ratio (SIR) level over conventional blind algorithms.
