Dynamic hardware-oriented algorithm for Angle of Arrival positioning technique

Abstract

There is an increasing demand for finding a mobile location in areas such as robotics applications, electronic warfare positioning, wireless communication systems and vehicle security. Angle of Arrival (AOA) is one of the key techniques in wireless location estimation. Location estimation is done by using standard triangulation operations that are usually implemented in software. In this paper, we present a new hardware-oriented algorithm that uses only simple shift and add operations in the computation and therefore can be easily implemented in hardware. The comparison between this method and the conventional AOA based positioning technique is discussed in terms of computational cost (required number of operations). The results show that the proposed algorithm outperforms the traditional one in terms of both software and hardware implementations points of views. © 2007 IEEE.
