摘要：Radio frequency spectrum is considered to be an expensive resource to the users. Its efficient utilization is possible using Smart or Adaptive Antenna array system to explore capabilities of wireless systems for optimization of service quality and capacity. Two major issues in smart antennas are Direction of Arrival (DOA) estimation and beamforming. The Direction of Arrival of all the incoming signals including the interfering signals is estimated using DOA algorithms. Some of the DOA algorithms are the MUSIC (Multiple Signal Classification), Root MUSIC, and ESPIRIT (Estimation of Signal Parameters via Rotational Invariance Techniques). Beam is steered in the direction of the desired signal and null are placed in the direction of the interfering signal. So, different beamforming algorithms are used like LMS, RLS. In this paper we have analyzed MUSIC Direction of Arrival (DOA) estimation and RLS algorithm for beamforming.
