Method and device for determining the fading coefficients of paths of a multi-path transmission channel linking, in particular, a base station and a cellular mobile telephone

摘要

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.
