Smart antenna base station beamformer for mobile communications

Abstract

A novel RLS beamforming algorithm with low complexity and high accuracy for applying in mobile communications smart antenna array processor is presented. The proposed pipelined structure has a higher performing that conventional RLS algorithm because require only vector operation and can be easy implemented en VLSI. As result proposed pipelined architecture can operate en N/k times faster than conventional RLS structure, where N and k are numbers of antenna elements and training samples respectively, and more, this algorithm have a minimum variance problem in finite precision implementation because one use the Householder transform procedure of weight vector updating.
