• The eigenspace in general represents the spatial characteristics of the propagation channel. Eigen-beam forming is one approach, which use the knowledge of the eigenspace of the channel at the transmitter or receiver to achieve a MIMO-capacity gain. However, the conventional EVD (Eigenvalue Decomposition) must repeat a high computation load every time the snapshot of correlation matrix is taken. In this paper, we propose an efficient tracking method based on the exact Jacobi method. Not only eigenspaces but also noisespaces can be obtained by this proposed method. The proposed method is applicable to slowly time-variant system. In such condition, the proposed method drastically reduces computation load compared with the conventional EVD method based on the Jacobi method.
