METHOD AND DEVICE FOR SEPARATING SIGNAL SOURCE

摘要

PROBLEM TO BE SOLVED: To provide a technique for separating a signal from a mixture of a 1st source signal related to a 1st source and a 2nd source signal related to a 2nd source. SOLUTION: Two signals are obtained first which represent two mixtures of the 1st source signal and 2nd source signal. Those two signals and at least one known statistical characteristic related to the 1st and 2nd sources are used and the 1st source signal is separated from the mixtures in a nonlinear signal domain without the need to use a reference signal.
