摘要： Signals received (14, 16) from channels exposed to multi-path propagation via a plurality of diversity antennas (12) and comprising at least one pilot signal are processed by detecting (18) a set of multi-path components for each of the received signal and computing (22) a set of channel coefficients from multi-path components of the at least one pilot signal in the set of multi-path components, wherein the set of channel coefficients is organized as a channel coefficient vector. From said channel coefficient vector, a set of combining weights (w) is estimated (22) to be applied (24) to the received signals by: - computing (22) a spatial correlation matrix of the channel coefficient vector by neglecting the correlations between multi-path components of the channel coefficient vector having different delays, whereby the correlation matrix is a block diagonal matrix comprising null coefficients other than for non-null sub-matrixes arranged along the diagonal of said correlation matrix, wherein said sub-matrixes have a size equal to the number of diversity antennas; - deriving (22) from the spatial correlation matrix a resulting matrix by calculating the inverse of said sub-matrixes or a scaled version thereof; and - multiplying (22) the resulting matrix and the channel coefficient vector in order to obtain the desired set of combining weights (w).
