DOA Estimation and Adaptive Beamforming for Smart Antenna System using DSP Algorithm

Abstract

In this paper a tool for the modeling analysis and simulation of direction-of-arrival (DOA) estimation and in the design of smart antenna arrays for wireless communication adaptive beam forming is needed. The use of studying adaptive beam forcing is to estimate the three different algorithms as MUSIC, MVDR and LMS. The directions of arrival and number of incident signals are estimated by the MUSIC and the arrival of desired signal is also given by MUSIC. The optimum weight vector will maximize the output signal to noise ratio and interference ratio (SNIR) of multiple antennas. So to obtain the optimum weight vector minimum variance distortion less response (MVDR) is used. LMS is very efficient and robust in application.
