ABSTRACT:
A device and method for predicting noise in a signal that is received by a digital receiver is provided. The device includes an autocorrelation function determination device and a noise predictor device. Also included in the device is an adaptive filter that produces a prediction error value for the received signal and the adaptive filter adjusts the filter coefficients as a function of a prediction error of the adaptive filter. Using the filter coefficient of the adaptive filter, the method may determine the autocorrelation function of the received signal. The noise estimated values for the noise contained in the received signal may be computed on a basis of the autocorrelation function of the received signal. The embodiment also may facilitate noise prediction when heavy correlated noise is present.
