Smart Antenna - DOA Estimation And Beam Forming Using MUSIC & LMS Algorithms
Subject area: Science,Engineering and Technology · Area of research: Electronics And Telecommunication Engineering
Abstract
This paper presents simulation results for a smart antenna system based on direction of arrival estimation and null steering. Direction of arrival (DOA) estimation is based on the MUSIC algorithm for identifying the directions of the desired signals and the null steering beamformer adapts the antenna pattern to steer the main beam towards the desired user and nullify all other interference. This system can be used to reduce multipath and co-channel interference. These benefits include the enhancement of coverage and the channel capacity, lower transmitted power, better signal quality, higher data rate and providing value-added services such as users position location (PL) and at the same time to minimize interference arising from other user by introducing nulls in their direction.
