PCT No. PCT/DE94/00553 Sec. 371 Date Nov. 28, 1995 Sec. 102(e) Date Nov. 28, 1995 PCT Filed May 6, 1994 PCT Pub. No. WO94/28652 PCT Pub. Date Dec. 8, 1994A process may be implemented which obtains a signal indicating a synchronization error between a pseudo-random signal sequence from a transmitter and a reference pseudo-random signal sequence from a receiver in a measuring device on the receiving end. In order to be able to detect a synchronization error as quickly and reliably as possible, successive sections (a, b, c) of a reference pseudo-random signal sequence (g'(n)) are each cross-correlated separately with the received pseudo-random signal sequence (g(n)), yielding partial cross-correlation functions (KKFa(n), KKFb(n) and KKFc(n)). The partial cross-correlation functions are added up to obtain a sum cross-correlation function (KKFs(n)). The sum cross-correlation function (KKFs(n)) is analyzed to detect the proper chronological occurrence of at least three maximums (ma, mb and mc). If the maximums (ma, mb and mc) do not occur at the proper times, a signal (synch) indicating a synchronization error is generated.
