Abstract: The procedure for estimation of the pulse response of an information transmission channel comprises an evaluation of the useful number (N2) of coefficients of the pulse response of the channel as a function of the real characteristics of the transmission channel. This includes the evaluation of a time spreading parameter (ds) for the transmission channel. The procedure for estimation of the pulse response of an information transmission channel comprises an evaluation of the useful number (N2) of coefficients of the pulse response of the channel as a function of the real characteristics of the transmission channel. A first estimation (30) of the pulse response is effected by using a predetermined maximum value for the number of coefficients of this pulse response. The evaluation of the useful number of coefficients comprises the evaluation of a time spreading parameter (ds) for the transmission channel, and the determination of a final estimation (H2) of the pulse response of the channel taking account of the useful number of coefficients.
