Extraction of Buried Signals in Noise: Correlated Processes

In this paper, we propose a method for extraction of signals correlated with noise in which they are buried. The proposed extraction method uses no a-priori information on the buried signal and works independently of the nature of noise, correlated or not with the signal, colored or white, Gaussian or not, and locations of its spectral extent. Extraction of buried correlated signals is achieved without averaging in the time or frequency domain.
