چکیده
This paper presents of Smart antenna system based on the direction of arrival (DOA) estimation and adaptive beamforming. Direction of arrival (DOA) estimation is based on the MUSIC for identify the direction of signal and adaptive beamforming is achieved by LMS algorithm. The smart antenna system designed involves a hardware part which provides real data measurement of the incident signal received by sensor array. Results obtained verify the improved performance of the smart antenna system .This take the form of sharper peaks in the MUSIC angular spectrum and deep nulls in the LMS array beam pattern.
