Abstract : This paper presents a simulation study of a smart antenna (SA) system based on direction-of-arrival (DOA) estimation is based on the MUltiple SIgnal Classification (MUSIC) algorithm for finding the Position Location (PL) of the desired user. The beamformer steer the main beam towards the desired user and nullify all other interferer, through adaptive beamforming using Least Mean Square (LMS) algorithm. This simulation results revealed the sharper peaks in the MUSIC angular spectrum and deep nulls in the LMS beam pattern. Also, this paper deals with DOA estimation and adaptive beamforming for the dynamic case based on SA. Eigen decomposing fined the PL of the desired user using MUSIC algorithm and steer the beam toward this user using compute the weight vectors like Least Mean Square (LMS) algorithm. Also this paper illustrates the results for the LMS error on the basis of iteration / sample.
