Abstract: A receiver is described, for instance for GSM systems, wherein a plurality of digital signals each comprising a training sequence (xp(t)) usable to generate an estimation of the transmission channel are received in diversity (A.1 . . . A.N) in the form of a plurality of replicas (10.1 . . . 10.N) each comprising a respective replica of the training sequence. The received digital signal is subjected to a delaying action thereby obtaining a plurality of versions of such signal, each comprising a respective set of signal replicas. Each version is subjected to a respective filtering action (23.1 . . . 23.N) independently from the other versions, by employing a respective first set of filtering coefficients (w*11 . . . w*N1 . . . w*Nj) obtained starting from a respective initial set of filtering coefficients.
