Abstract
For antijamming design of global positioning system (GPS) in military applications, the direction of arrival (DOA) estimation of jamming signal is positively necessary. The DOA estimation is also used in mobile communication systems to expand the coverage area or to increase the channel capacity, where the base station forms a beam to the direction of the user terminal. In this paper, we compare the performance of MUSIC and ESPRIT algorithms with two-dimensional antenna arrays. MUSIC and ESPRIT algorithms are two typical DOA estimation methods in nonparametric and parametric methods, respectively. With ESPRIT, we derive the estimates of two-dimensional azimuth and elevation from two one-dimensional DOAs. Computer simulations are shown to demonstrate the performance.
