Study and Analysis of MVDR DOA Estimation Algorithm xyz
Abstract
-The smart antenna (SA} can adjust the direction pattern adaptively and reduce the interference signals using some adaptive interference mulling algorithms, and thus enhances the performance of mobile telecommunication system, especially enlarges the user capacity of system. The smart antenna system is mainly applied to the base station (BS) now, but next step, the smart antenna technology will be applied to mobile station (MS) along with hardware and software in MS becoming more powerful. The smart antenna system will be applied in both BS and MS in next generation mobile telecommunication system.
However, performance of smart antenna system greatly depends on efficiency of digital signal processing algorithms. The algorithm uses the Direction of Arrival (DOA) algorithms to estimate the number of incidents plane waves on the antenna array and their angle of incidence. In this paper the performance of Direction-of-Arrival (DOA) algorithm MVDR is investigated. The simulation results show that, the advantages in performance of one algorithm over another vary with the conditions and is significantly influenced by both of the environments well as the system. Thus, careful consideration is imperative to the conditions and system parameters specific to the planned deployment. The algorithms have been simulated in MATLAB 7.4 version.
