Device for blind source separation and hardware apparatus having plurality of the same coupled in parallel configuration

摘要

An unknown signal separation device comprising a forward processor and an update processor including a plurality of processing elements and an update element connected in a systolic array form is disclosed. The forward processor receives one or more unknown signal vectors x for a predetermined time L (L is a delay threshold of the voice mixing model, where L is a sampling frequency multiplied by a maximum reflection delay time) to separate a predetermined unknown signal. An algorithm is applied to output an output signal vector y , and the update processor receives the output signal vector for a predetermined time 2L and learns coefficients input to an unknown signal separation algorithm applied to the forward processor. According to the present invention, the unknown signal separation operation can be performed at high speed, and the processing capacity can be easily expanded.
