Proposal of a nonlinear echo canceller that uses Gaussian process
Jyunichiro Tomita, Yuzo Hirai (Tsukuba Univ.) NC2008-7
Abstract (in Japanese) (See Japanese page) 
(in English) Gaussian process (GP) is a process where the joint distribution over variables is specified completely by the second-order
statistics, namely the mean and the covariance. Because the output data is estimated by a training data set and a test data set,
it is though that the influence on the convergence characteristic is small. In this paper, we confirm that both of linear echo-path
and nonlinear echo-path follow Gaussian distributions. Furthermore, we propose a nonlinear echo-canceller that uses
Gaussian process, and analyze the convergence characteristic of ERLE for stationary colored signal to ensure that Gaussian process
can cancel the echo.
