Realization, comparative analysis of angle of arrival computation for adaptive antenna array topology

Adaptive antenna array system continuously checks and tracks coverage areas. This system fixes the direction of signal of interest, provides antenna radiation pattern maxima directing in the signal of interest and zeros or nulls in the direction of unwanted signals. To do this work smartly wide variety of algorithms are designed. High requirements in the terms of accuracy and processing power are the key features in these algorithms and many of them satisfy these criteria. In this paper MUSIC, ESPRIT, Improved MUSIC algorithms are realized, compared and analyzed for adaptive antenna array topology with the help of simulation using MATLAB.
