Early - late - correlation to the timing error correction in the data communication receivers

摘要

A timing error correction art for use in data communication receivers such as, for example, wlan - receivers (wlan: wireless local area network, wireless local area network) is provided, in which an input signal is received, the a timing error, the timing error is corrected and a signal with a corrected timing error is output. The timing error correction comprises performing a early - late - correlation to the signal representing the corrected timing error. The early - late - correlation comprises the generation of at least one early - and late - sample pair, the generating an error signal of the difference between said early - sample and the late - sample, and the generation of at least one control signal on the basis of the error signal. A time offset correction algorithm is carried out as a function of the control signal.
