METHOD AND APPARATUS FOR BLIND SOURCE EXTRACTION

摘要

PURPOSE: A method for extracting a blind signal is provided to efficiently extract a signal from a source close to a receiver or a source in a specific direction. CONSTITUTION: A receiving unit includes two or more receivers(20,22). The receiving unit receives a signal. A transfer function producing unit produces a transfer function for demixing. A demixing unit(30) demixes the received signal by using the produced transfer function. The transfer function is determined to extract the signal from a source(10,12) close to the receiver.
