foerfarande foer finavstaemning of a transversalekvalisator as anvaends in a receiver in a dataoeverfoeringssystem

摘要

The invention relates to a method for the fine-tuning of a transversal equalizer used in the receiver of a data communication system by means of a short, non-periodic signal sequence contained in the received signal immediately after the determination of the initial values of the equalizer coefficients on the basis of a received training sequence. The time required for the fine-tuning and the used signal sequence can be substantially reduced when only pan of the frequency components of the equalizer transfer function are subjected to fine-tuning while the rest maintain the values they had before the fine-tuning.
