摘要：
The invention relates to a process for obtaining a signal from a measuring device on the transmission side indicating a synchronisation error between a pseudo-random signal sequence from a transmitter and a reference pseudo-random signal sequence from a receiver. In order to detect the synchronisation error as quickly and reliably as possible, successive sections (a, b, c) of the reference pseudo-random signal sequence (g'(n)) are cross-correlated with the received pseudo-random signal sequence (g(n)), obtaining a partial cross-correlation function (KKFa(n), KKFb(n) and KKFc(n)); the partial cross-correlation functions are added to obtain a sum cross-correlation function (KKFs(n)) which is examined for the appearance at the right time of at least three maxima (ma, mb, and mc). If the maxima (ma, mb and mc) do not appear at the right time, a signal (synch) indicating a synchronisation error is generated.
