Method for estimating the impulse response of a receiving channel, device and corresponding program.

Abstract

Method for estimating the impulse response of a receiving channel, device, and corresponding program. The present invention relates to a device and a method for calculating an estimate of the impulse response of a receiving channel to a signal. Such a method comprises at least one iteration of the following steps: obtaining (E1) a signal comprising at least p sequences of received Np pilots; predicting (E2), based on said at least p sequences of received Np pilots and a first previously trained neural network NN1, a covariance matrix of the process noise of a Kalman filter with a current time step k; calculating (E4), from the covariance matrix of the process noise and parameters of the current time step k of the Kalman filter, said estimate of the channel impulse response. Figure for the abstract: Fig. 2.

Claims
