Abstract: In many communication systems, one is interested in point to point communication and for this, a highly directive beam of radiation is required. In this study, the performance of DOA estimation based upon (recursive unitary MUSIC algorithm) RUMA was proposed. The basic of RUMA is dealing with real-valued matrices and BiSVD subspace tracking method to carry out iterative DOA estimation without heavy (eigen-value decomposition) EVD or (singular-value decomposition) SVD. To investigate the computational time and accuracy of DOA estimation proposed method, first develop the antenna array model for DOA estimation then modified recursive unitary MUSIC matrix data. Simulation result shows the accuracy of DOA estimation better under no mutual coupling effects between the antennas by adding an unitary type of algorithm and computational time improved even with the increase of number of array elements.
