This paper proposes a new method to identify parameters of an SISO DLTI system under non-white non-stationary gaussian stochastic noises, such as time varying colored noises. The method improves the estimation accuracy by prewhitening the noise with a linear time varying filter, which is derived from the wavelet packet analysis.
