Abstract: A process for estimating a speed of movement of a mobile terminal operating in a wireless communication system and communicating with a base station via a transmission channel includes estimating fading of the transmission channel, and performing an autocorrelation on the fading for providing a first autocorrelation result. Reference autocorrelation results are calculated for predetermined values of speed of movement of the mobile terminal, with the calculating being based upon a known autocorrelation function performed on the fading. The process further includes comparing the first autocorrelation result to the various reference autocorrelation results, and estimating the speed of movement of the mobile terminal based upon the comparison.

Abstract: A method for estimating the impulse response of an information transmission channel includes evaluating a useful number of coefficients of an impulse response of the information transmission channel as a function of actual characteristics of the information transmission channel. This evaluation is carried out, for example, by using a time domain spreading parameter of the channel.

Abstract: First estimations of the fading coefficients of a multi-path transmission channel are carried out in the sense of maximum likelihood. Sets of Wiener filter coefficients are stored according to predetermined speeds of movement of the mobile terminal and predetermined power levels of the signal. The real speed of the mobile terminal is estimated and the power of the signal for each path is measured. From this, a set of Wiener filter coefficients is derived with which the first estimations are filtered to obtain the final estimation of the fading coefficients.
