Abstract (en)
[origin: FR2762167A1] The invention concerns a method for estimating a communication path formed by several channels. Said method requiring an estimation of the impulse response function (C1, C2, ..., Cn) of said channels comprises the following steps: acquiring a spatial statistic of said communication path; establishing a corrected impulse response function (C'1, C'2, ..., C'n) at least by weighting the pulse response functions (C1, C2, ..., Cn) using the spatial statistic and an additive noise estimation (N01, N02, ..., N0n) of these channels.
