A method of blindly separating a signal, wherein, for at least one source, a filter uniquely defined for a source is determined for each source, the method comprising the steps of: applying an inverse filter corresponding to inverse of the filter to one or more of multiple outputs of the received signal so as to restore property of the corresponding source; and adjusting gain of each of outputs which have been filtered by the inverse filter, under constraint that a sum of weighted multiplexed filtering output signals has the same property as an original signal of the corresponding source, in order to remove other sources or interfering signals which occupy the same frequency band or transmission time interval.
