| Abstract(in English) | In the sound separation, it is in use that blind source separation which estimates separation parameters for the probability distributions and mixing process of signals as unknown characteristics. However, if these characteristics are available, it may be expected that improvement in the separation performance. In this paper, when a mixing process of observation signals may approximate by the first order lag system, it is proposed that a method for estimation of separation parameters, and the fundamental performance is examined. As a result of a simulation to artificial mixed sounds, as compared with the method for estimation the coefficients of z-transform of the separation filter, it was obtained that the result which improves the cross talk oppression performance by about 3 to 25 times. |
