POSTPROCESSING APPARATUS AND METHOD FOR REMOVING CROSS-CHANNEL INTERFERENCE AND APPARATUS AND METHOD FOR SEPARATING MULTI-CHANNEL SOURCES EMPLOYING THE SAME |
摘要 |
Cross-channel interference is eliminated and multi-channel sources are separated by estimating a source absence probability for a current frame of a first channel output, and determining an interference elimination coefficient for matching a secondary signal of the first channel output with a primary signal of a second channel output by using the source absence probability, generating an interference signal by multiplying the second channel output by an over-subtraction factor and the interference elimination coefficient, wherein a partial differentiation is performed for a v-norm value of a spectral amplitude difference, between the first channel output and the second channel output multiplied by the interference elimination coefficient and a result of multiplication of the source absence probability, by using the interference elimination coefficient to determine an update amount of the interference elimination coefficient for a next frame. |
