method for taktimpulssynchronisation a empfaengers to demodulate a vierphasenkodierten datensignals and taktimpulssynchronisationsanordnung for implementation of this method

摘要

The invention relates to a method for the clock synchronization of a receiver for demodulating a quadphase coded data signal and to a clock synchronization device for carrying out the method. In the method according to the invention the first bit is compared (correlated) with the third bit and the second bit with the fourth bit: a high degree of correlation indicates that synchronization has been obtained and a low degree indicates absence of synchronization.
