Abstract

The performance of the smart antennas greatly relies on the efficient estimation of direction of arrival. Therefore, the authors have addressed and analyzed high resolution subspace based algorithms to evaluate the performance for accurate estimation of direction- of- arrival (DOA) of signals impinging on uniform linear array (ULA). Simulation results showed that Matrix Pencil provides better performance in terms of root mean square error (RMSE) and probability of resolution; although its performance is not as good as Root-MUSIC algorithm for closely spaced signals. Profound analysis of these algorithms can be used to determine the direction of arrival of the signals at ULA.
