Abstract

A WLAN (Wireless Local Area Network) receiver with a synchronization unit is provided, wherein the synchronization unit comprises a frequency error correction unit configured to perform a frequency error correction process, a phase error correction unit configured to perform a phase error correction process, a filter circuit capable of applying one of at least two different filter transfer functions, wherein a first one of said at least two different filter transfer functions is a frequency error correction filter transfer function for use in said frequency error correction process and a second one of said at least two different filter transfer functions is a phase error correction filter transfer function for use in said phase error correction process, and a controller unit connected to said filter circuit to select one of said at least two different filter transfer functions.
