Abstract

Synkronisering mellom en sender og en mottaker (fig. 2; fig. 3) utfores ved koding og overforing av en synkroniser- ingspuls som en serie av m forste bølge- former etterfulgt av en serie av n andre bølgeformer. De første og andre bølge- former er av samme varighet og overfores i fase raed hverandre, og m og n er posi- tive, reelle tall, idet m er større enn én. Den andre bølgeform er forskjel- lig fra den forste og er fortrinnsvis negativt korrelert med denne. Når mot- takeren (fig. 2; fig. 3) detekterer en serie av forsto bølgeformer i det mottatte signal, genererer den lokalt (212; 312) en serie av (enton forste eller andre) bølgeformer og korrelerer (206; 314; 316; 318) det lokalt genererte signal med det mottatte signal. En endring i korrelasjon detekteres som synkroni- seringspulsen.
