Patent ID: 7190709

Claim:
A WLAN (Wireless Local Area Network) receiver having a timing error correction unit comprising: a time offset correction unit connected to receive an input signal having a timing error and output a signal having a corrected timing error, said time offset correction unit being adapted to perform a time offset correction algorithm to correct said timing error; a sample pair generation unit connected to receive the output signal of said time offset correction unit and adapted to generate at least one sample pair therefrom, said at least one sample pair comprising an early sample and a late sample; a difference computation unit connected to receive said at least one sample pair and adapted to generate an error signal indicative of the difference between the value of the early sample and the value of the late sample of the received sample pair; and a control unit connected to receive said error signal and adapted to generate at least one control signal therefrom, said control unit being connected to said time offset correction unit to provide said at least one control signal to said time offset correction unit to control said time offset correction algorithm, wherein said control unit is adapted to detect an integer time shift and a fractional time shift in said error signal.
