During the synchronization, a first, analog carrier signal (bs) exhibits a predetermined phase position at least temporarily. A further reference carrier signal (rs) is modulated with the same prescribable phase position, the phase difference between the two modulated carrier signals (bs, ts) is identified...http://www.google.fr/patents/US6798855?utm_source=gb-gplus-shareBrevet US6798855 - Method and arrangement for fast synchronization of two carrier signals
