Abstract
In this paper, therefore, we try to evaluate the estimation performance of both the number of waves and DOA. It is just the performance evaluation of overall DOA estimation. In addition, we propose the procedure which enhances the estimation accuracy of DOA by using the estimated number of waves and estimated DOA along with the likelihood function of DOA. Comparing the EVD (eigenvalue-decomposition)-based method, e.g. MUSIC, and non-EVD-based method in computer simulation, we demonstrate the effectiveness of the proposed procedure.
