Abstract
The invention concerns a method and circuitry for compensating internal timing errors of a mobile station, particularly those of a digital mobile station. According to the invention, the signal samples that include the maximum amount of energy and the position signals (maxpos) of these maximum signal samples are, by means of a correlator (8), determined from a channel impulse response estimated in a way known in the art, and in a timing unit (6), with help of successive position signals (maxpos), a correction signal is determined that indicates the magnitude and direction of the timing error of the mobile station, and by said correction signal the ting of the mobile station and particularly that of its clock system is checked and, if necessary, synchronized.
