Abstract
Direction-Of-Arrival (DOA) estimation is one of significant techniques for high-speed mobile communication to know wave propagation environment [1]. High resolution DOA estimation algorithms like MUSIC [2], and ESPRIT [3] have already been widely used in many wireless communication applications. Generally planar array structures are used for 2-D DOA estimation. Planar arrays often well estimate azimuth angles but cannot well estimate elevation angles because of short antenna aperture in elevation direction. Therefore we try to develop a 3-D array configuration which well estimate both azimuth and elevation angles.
