Abstract
This paper presents smart antenna using direction of arrival estimation and beamforming Direction of arrival (DOA) estimation is based on the PM 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 different drawbacks present in existed system like 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 user’s position location (PL) and at the same time to minimize interference arising from other user by introducing nulls in their direction. Also this paper deals with adaptive beam forming approach for the dynamic case based on smart antennas and adaptive algorithms used to compute the complex weights like Least Mean Square (LMS) algorithm.
