DEVICE WITH ADAPTIVE EQUALIZER

摘要

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.
