Abstract :
DOA estimation plays an important role in array signal processing, and has a wide range of application. In this thesis, I will describe what DOA (Direction of arrival) estimation is, and give a mathematical model of DOA estimation. Then estimate DOA based on the MUSIC algorithm, and give some simulations with MATLAB to simulate what factors can affect the accuracy and resolution of DOA estimation when using the MUSIC algorithm. An angle of arrival (AOA) estimator is presented. Many applications require accurate AOA estimates such as wireless positioning and signal enhancement using space-processing techniques. This paper examines methods of Direction finding TOA, TDOA, and AOA. Experimental results confirm the methods success. Signal routing is very important in telecommunications and we have explained some methods in this article and specifically we have explained an aoa method. We described the results and simulations in the result section. We compared our method with other methods and our method shows a better result.
