Implementation of Narrowband Conventional and Adaptive Beamformers for Smart Antenna Systems

Abstract: This study presents three important narrow band Beamformers for smart antennas; conventional phases shift, adaptive Minimum Variance Distortion less Response Beamformer (MVDR) and adaptive Linear Constraint Minimum Variance Beamformer (LCMV). The conventional phases shift beamformer in presence of strong interference signals we cannot exactly extract the signal content. Based on the received signal weight vector these beamformers form beam pattern. In self-nulling condition LCMV beamformer is efficient than the MVDR beamformer even though the interference signal direction is close to the desired signal direction. The nine elements uniform linear array (ULA) with λ/2 element spacing smart antenna is used in our simulation program.
