Abstract
The invention relates to a method and a system for estimating a symbol time error in a broadband transmission system, comprising: - determination a timing error signal of an input-signal of a discrete Fourier-transformation block (5) in a data symbol stream on the basis of intersymbol correlation using a predetermined period in each received symbol, - selecting as a predetermined period a number of samples of different useful data parts of a symbol, - determining the time error value (ε) based on the intersymbol interference of the selected samples of the different parts of said symbol.
