    This paper presents a smart antenna system using a combination of nonconventional least square (NCLS) optimization and direct data domain least square (D3LS) for direction-of-arrival (DOA) estimation and beamforming, respectively. In the proposed system, NCLS optimization is utilized to estimate DOA of incoming signal first. The estimated DOA is then assisted for initial processing of D3LS in beamforming. The performance in term of estimated signal amplitude and estimated DOA of the proposed system is evaluated via simulations. © 2012 IEEE.
