Free registration required

Executive Summary

The aim of this paper is to combine smart antenna beamforming and RAKE receiver in Wideband Code Division Multiple Access (WCDMA). The proposed method combines spatial diversity as well as temporal diversity to improve the performance and overcome both interferences and multipath fading. This investigation has focused on one of the new proposed blind beamforming algorithms. It is based on Constrained Constant Modulus (CCM) algorithm which is used for deriving a Recursive-Least-Squares (RLS-) type optimization algorithm.
