Implementation of MUSIC Algorithm for a Smart Antenna System for Mobile Communications
This paper presents practical design of a smart antenna system based on direction-of-arrival estimation and adaptive beam forming. Direction-Of-Arrival (DOA) estimation is based on the MUSIC algorithm for identifying the directions of the source signals incident on the sensor array comprising the smart antenna system. Adaptive beam forming is achieved using the LMS algorithm for directing the main beam towards the desired source signals and generating deep nulls in the directions of interfering signals. The smart antenna system designed involves a hardware part which provides real data measurements of the incident signals received by the sensor array.
