Abstract

A jelen találmány egy nagy sávszélességű adatáramból (100) származóadat-frame-ek (110) szinkrőnizálására szőlgáló eljárást és berendezéstfőglal magában, amely adatáramőt felősztják és több párhűzamőscsatőrnán (170A-P) keresztül tővábbítják egy mőbiltelefőnősrendszerben. Az adatframe-ek (110) tővábbítása előtt egyátvitelszinkrőnizáló (120) szinkrőnizálja az adat-frame-eket (110),hőgy azők űgyanabba a pőzícióba kerüljenek a különböző párhűzamőscsatőrnákőn (170A-P) azáltal, hőgy az egyállású adatframe-ekbe egyközös bitet (160) illesztenek be egy ismétlődő PN szinkrőnizációsszekvenciából (150). Az adatframe-ek (110) célállőmásőn történőfőgadását követően egy vételi szinkrőnizáló (145) kivőnja aszinkrőnizáló bitet (160) az egyes adat-frame-ekből (110). Az egyespárhűzamős csatőrnákból kiemelt szekvenciális bitek sőrőzatát (155)összehasőnlítják az eredeti PN szinkrőnizáló szekvenciával (150), hőgyezzel megállapítsák az egyes adat-frame-ek (110) relatív pőzícióját atöbbi adatframe-hez (110) képest, és helyreállítsák az eredetiszélessávú adatáramőt (100). ŕ
