ABSTRACT:
A method of estimating a communication path formed of a plurality of channels, the method necessitating an estimate of the impulse response C1, C2, . . . , Cnof the channels, including the following steps of (1) acquiring a space statistic of the transmission path, and (2) establishing a corrected impulse response (C1, C2, . . . , Cn) at least by weighting the impulse responce estimates (C1, C2, . . . , Cn) by the space statistic and an estimate of the additive noise (N01, N02, . . . , N0n) of the channels.
