摘要：
In this paper, we propose a novel system architecture that employs flexible tree search based orthogonal matching pursuit (FTB-OMP) algorithm for direction of arrival estimation. It is shown by simulation results that the FTB-OMP algorithm has high estimation performance and resolution capability when compared to the MUSIC and OMP algorithms. The proposed system does not require apriori knowledge on the number of directions to be resolved and uses very small amount of snapshots for convergence. It is also superior to ESPRIT algorithm since ESPRIT cannot resolve angles that are separated more than a threshold.
