Performance Analysis of Beamforming Based on DOA for Smart Antenna Systems
نویسنده
چکیده
This paper presents the DOA based adaptivebeamforming algorithm of smart antenna systems for mobile communications.Two stages are involved to control the radiation pattern, while maximizing the signal power towards the desired direction and suppressing the interference from undesired direction. The first stage consists of estimating the directions of arrival of all wave fronts impinging on an array. The second stage involves placing deep nulls in the directions of the interferers. Simulations are performed to investigate the performance of the algorithm.
