New accelerated adaptive beamforming algorithm

This paper is concerned with a new accelerated RLS adaptive beamforming algorithm applied to fast moving mobile terminals. The proposed algorithm is based on the internal model principle by approximately expressing the parameter changes in terms of polynomial time functions, and can rapidly track the multipath fading environment. We show that the amount of calculation of the proposed algorithm is almost the same as that of the ordinary RLS adaptive beam-forming, and its effectiveness is examined in numerical simulations.
