Best Performance Analysis of DOA Estimation Algorithms

The performance of smart antennas is highly dependent on accurate estimation of the access route (DOA). In this paper analysed various techniques for assessing DOA and check the performance. The simulation results show that the Super-Resolution algorithm outperforms conventional and sub-space techniques in terms of angle accuracy, performance efficiency and number of elements in the antenna array. Higher resolution algorithm and statistically is more efficient than others technique, and more suitable for fifth generation networks. The aim of this paper is to analyse the DoA techniques and to achieve the best performance in terms of beam accuracy at extreme convergence of angles. The following techniques will be analysed in this paper: Beam-scan, MIN-NORM, minimum variance distortion less response (MVDR) and Super-Resolution algorithm or Multiple Signal Classification (MUSIC).
