Abstract

Nowadays mobile users require increased coverage, quality of service and capacity in wireless communications. By using adaptive antennas at both transmitter and receiver in wireless communication, we can easily reach the required improvement. In this paper Adaptive Antenna plays a major role to improve the performance of wireless communication systems. This antenna uses advanced signal processor that modifies self generated beam pattern to strengthen the desired signal and reduce the unwanted signal. This type of antenna is called as smart antenna. This paper presents the adaptive array antenna fundamentals, direction of arrival and several digital beamforming algorithms. Performance analysis of the MUSIC algorithm with LMS is studied because these results are useful for the smart antenna system design. All the simulations are carried out using MATLAB.
