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.

Method 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.
System for estimating a symbol time error in a broadband transmission system, which receives a data symbol stream from a transmitter comprising:
- a symbol time error estimator for determination a timing error signal of a digital input-signal of a discrete Fourier-transformation block in the data symbol stream on the basis of intersymbol correlation using a predetermined period in each received symbol, wherein a number of samples of different useful data parts of a symbol are selected as a predetermined period and the time error value (ε) is determined on the base of the intersymbol interference of the selected samples of the different parts of said symbol.
