TL;DR: In this article, a data stream consisting of synchronization words and data words is received from a medium and the information received is always consecutively stored in a buffer memory, which is connected to a detection device for generating an instantaneous synchronization signal by way of a majority decision on at least three correctly received synchronization words.

Abstract: A data stream is received from a medium. This stream consists of synchronization words and data words. The synchronization words are either identical or one the inverse of the other when they are correctly received. Between two synchronization words a fixed number of n data words is present. The information received is always consecutively stored in a buffer memory. The buffer memory has connected to it a detection device for generating an instantaneous synchronization signal by way of a majority decision on at least three correctly received synchronization words. Preferably, the buffer memory is a shift register comprising a data output which is situated approximately 1/2n data words +1/2 synchronization word beyond the center of the shift register when n has an even value.

Method and device for extracting a synchronizing signal from an incoming PCM signal
Jarus Daniel Jan
- 25 Sep 1978
TL;DR: In this paper, a first circuit searches for the synchronizing signal in a fixed position in the received signal every time it should occur, and if this circuit does not find the synchronising signal when it should, a second circuit starts a search action for it in the sent signal.
