摘要: The initial values of parameter estimates are set, including reverberation estimates, which includes a regression coefficient used in linear convolutional operation for calculating an estimated value included observed signal, source prediction and residual power that identify the spectrum noise include estimates. Then, maximum likelihood estimation is to alternately repeat processing updating at least one until predetermined termination condition satisfied.
