Abstract
A timing error correction technique for use in data communications receivers such as WLAN (Wireless Local Area Network) receivers is provided where an input signal is received that has a timing error, the timing error is corrected, and a signal having a corrected timing error is output. The timing error correction comprises performing an early-late correlation on the signal that has the corrected timing error. The early-late correlation comprises the generation of at least one early and late sample pair, the generation of an error signal that is indicative of the difference between the early and late samples, and the generation of at least one control signal based on the error signal. A time offset correction algorithm is performed dependent on the control signal.
