Location estimation algorithm using smart antenna

This paper propose user location estimation method which uses smart antenna based reception direction. Existing AOA method is capable of producing error due to the change of azimuth. The range of error increases as the distance between a terminal and base station increases. In order to solve this problem, the method of measuring the reception direction of signal and TOA from several branches can be proposed. Our proposed method is verified by creating same error of azimuth environment by using variety of computer simulations. Our proposal of location estimation method shows increased performance of location estimation than AOA method.
