Summary:
The noise cancellation technologies are useful for speech recognition and other applications. There are some kind of methods for cancellation of background noise. In this paper, The desired signals are separated from background noise by using proposed PCA-ICA method (Principal Component Analysis, Independent Component Analysis). The proposed PCA-ICA method requires several number of observed signals that is, the same as the number of sources. The noise signal can be removed in the same way as BSS (Blind Source Separation). We have done experiments (two-observation one-source one-noise, with delay) and evaluated the results.
