Abstract :
Different beamforming algorithms like side-lobe cancellors, linearly constrained minimum variance (LCMV), least mean squares (LMS), recursive LMS, and direction of arrival (DOA) exist in literature. Among the direction of arrival (DOA) algorithms, MUSIC and ESPRIT play the most important role. These two algorithms were implemented and their performances were compared. The algorithms were simulated for different signal levels and the DOAs were computed for use in next generation wireless. ESPRIT was found to be a better DOA technique for uncorrelated source used in beamforming.
