Zusammenfassung:	A device ( 200 ) with an adaptive equalizer ( 210 ) includes an adaption scheme performed in the synchronous domain. The equalizer coefficient update scheme is based on a correlation of an error sequence (delta k) derived from the equalized sequence transposed to the synchronous domain (Ek) and a synchronous and delayed version (Jk) of a vector of the equalizer tap values (Vn). The result of the correlation is further passed through an arrangement of integrators ( 226 ) and a temporal interpolator ( 228 ). The vector of equalizer tap values is converted into the synchronous domain by means of a bank of sampling rate converters ( 230 ) of which the overall implementation ( 300 ) can be simplified.
