| Research Abstract |
The blind source separation and specification of location on time-frequency domain considering time lag information were conducted. Especially, mathematical formation of the separation method of the source signal embedded in the noise was presented. The numerical test was conducted to confirm our method. and then the separation and specification of location of the source signal and the noise can be done by high accuracy.
