BLIND SOURCE SEPARATION METHOD USING SUBORDINATE RELATIONSHIP BETWEEN HARMONIC FREQUENCIES AND DEMIXING SYSTEM USING SAME

摘要

According to the present invention, a blind source separation method and, more particularly, a method for separating signals in a frequency domain comprises the steps of: mixing and receiving signals from two or more sound sources; and demixing the received signals by assuming the dependency between frequency bins included in the same harmonic frequency group among a plurality of harmonic frequency groups.
