In this paper, we propose a method for selection of correlation matrices that yields a better separation performance for Noisy BSS, in which only stationarity is imposed on the noise, based on joint diagonalization of differences of correlation matrices.
In the proposed method, we adopt the correlation matrices by which the residual noise component is relatively small in their differences.
We also confirming that the proposed method achieves a better separation performance by some numerical experiments with speech and music signals. |
