Direction of arrival estimation by using standard communication technologies in indoor environment

Recently, direction of arrival estimation has become a significant information to obtain the position of mobile devices which they have wireless communication technologies. The accuracy of the direction of arrival (DOA) estimation has a crucial role to determine the position of these devices, such as robots, vehicles etc. An antenna array structure makes possible to estimate direction of arrival angle by using the several array signal processing techniques. The primary aim of this study to obtain the DOA estimation and can be applied with any distance position techniques, for using in low-profile devices to acquire 1-D indoor position of mobile devices. The multiple signal classification method is almost used with all geometric array configurations to determine the direction of arrival angle of the incoming signal. In this dissertation, we will apply MUSIC algorithm one by one to the uniform liner array, the uniform circular array and the L-shaped array geometric configurations. Moreover, we perform a MATLAB based simulation to combine all the results, to improve the accuracy of the DOA estimations.
