Abstract
There is provided a non-linear signal separation method using the non-linear state space projection method capable of separating an effective non-linear signal even if the S/N ratio is low by performing the time domain high speed non-linear state space projection when a signal is a multi-channel signal and has a periodicity. In the non-linear signal separation method using the non-linear state space projection method, an original signal having a complex signal which is a multi-channel and cyclic signal measured from one phenomenon is processed by using the time domain high-speed non-linear state space projection method so as to estimate a noise in the original signal and subtract the estimated noise from the original signal, thereby separating the signal to be measured in the original signal as a non-linear signal even when the S/N ratio is low.
