| Abstract(in English) | Rank-constrained spatial covariance matrix estimation (RCSCME) is a method for blind speech extraction. In RCSCME, we derive a more appropriate complementation method compared with the conventional complementation method from the consideration for the process that the spatial covariance matrix (SCM) of noise becomes rank-deficient. Then, we show the property of the common part of the conventional and proposed complementation methods. Furthermore, it is shown that the SCM of noise is included in the common part with ideal preprocessing of RCSCME. To confirm this experimentally, we propose RCSCME based on the new complementation method corresponding to the process of rank dificiency, and conduct several experiments to show that the SCM of noise is estimated in the region close to the common part and it is useful to constrain the SCM of noise to the common part. |
