Patent ID: 6954618

Claim:
A method for determining fading coefficients of paths of a multi-path transmission channel linking a base station and a mobile terminal, the method comprising: determining first estimation values of the fading coefficients in a sense of maximum likelihood; storing sets of coefficients of a Wiener filter respectively precalculated for sets of different predetermined values of speed of movement of the mobile terminal and of power of a signal, using an autocorrelation function that is assumed to be known for the fading coefficients; estimating the speed of movement of the mobile terminal and of the power of the signal of each path; selecting for each path a set of precalculated Wiener filter coefficients based upon a comparison between the estimated speed of movement and the power of the signal, and the sets of predetermined values of the speed of movement and of the power of the signal; and determining the fading coefficients obtained by filtering the first corresponding estimation values using the selected sets of precalculated Wiener coefficients.
