| Abstract(in English) | This paper proposes the selection scheme of DOA estimation algorithms by eigenvector analysis in angular spread environment. In angular spread environment, depending on phase and amplitude of the scattering waves, performance of MUSIC algorithm is deteriorated. MUSIC using gradient type mode vectors can improve performance above environment, however this algorithm has also the environments that performance is deteriorated. To improve performance of DOA estimation, the proposed scheme selects the better algorithm from above MUSIC algorithms based on eigenvector analysis. Performance evaluation of DOA estimation by computer simulation conforms that the proposed scheme is effective in improving performance of DOA estimation compared to that of MUSIC algorithm. |
