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...
SUMWE (SUbspace-based Method Without Eigendecompositon) is one of the high-resolution DOA (Direction Of Arrival) estimation methods for coherent waves [1]. SUMWE employs spectrum peak search in DOA estimation like MUSIC method [2], that often leads large computational cost. Recalling that Root-MUSIC method [3] without spectrum peak search greatly reduces the computational cost, similar root-finding...
