This paper presents a tool for the analysis, and simulation of Direction-Of-Arrival (DOA) estimation in wireless mobile communication systems over the fading channel. It reviews two methods of Direction Of Arrival (DOA) estimation algorithm. The standard MUltiple SIgnal Classification (MUSIC) can be obtained from the subspace based methods. In improved MUSIC procedure called Cyclic MUSIC, it can automatically classify the signals as desired and undesired based on the known spectral correlation property and estimate only the desired signal's DOA.
