Keywords:
Smart antenna, beamforming, LMS algorithm, RLS algorithm, SMI algorithmAbstract
A comparative study of beamforming techniques using combined algorithms, like, sample matrix inversion with least mean square (SMI-LMS), sample matrix inversion with recursive least square (SMI-RLS) and least mean square with recursive least square (LMS-RLS) algorithm is presented in this paper. Side lobe level, null depth and error plot of adaptive beam formation for different signal-to-noise (SNR) with different element spacing are simulated and compared. It is found that performance of LMS-RLS algorithm is better than SMI-LMS and SMI-RLS algorithm.
