Direction of Arrival (DOA) estimation technique has been lately used to determine the location of mobile devices. Using array antennas with the help of signal processing makes it possible to effectively identify the location or direction of the user. Some well-known DOA estimation algorithms have been proposed such as delay and sum method, Capon's minimum variance method, subspace method with MUSIC algorithm, DOA estimation under coherent signal conditions and the integrated approach to DOA estimation. From literatures, there has not been a demonstration regarding the appropriate parameters for those algorithms for various environments such as indoor or outdoor scenarios. This paper adopts LTE fading channel models to analyze the optimal parameters of some famous DOA estimation algorithms.
