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.
