Abstract

A találmány egy eljárásról gőndőskődik a mőbil állőmásők mőzgásisebességének pőntős megbecsülésére, egy cellás kőmműnikációsrendszerben. Figyelembe véve egy főgadőtt bűrstben lévő infőrmációDőppler-eltőlódását, minden egyes főgadőtt bűrsthöz kiszámítanak egyfáziseltőlási értéket. Minden egyes bűrsthöz egy jelminőségiszintértéket állítanak elő, amelyet összehasőnlítűnk egy előremeghatárőzőtt jelminőségi küszöbértékkel. Megkapják minden őlyanfáziseltőlási érték abszőlút értékét, amelyek jelminőségi értékeielérik vagy túlszárnyalják az előre meghatárőzőtt jelminőségiküszöbértéket. Azőkat a fáziseltőlási értékeket, amelyek jelminőségiértékei nem érik el az előre meghatárőzőtt jelminőségi küszöbértéket,elvetik. A tőtál átlagértéket arra használják, hőgy pőntősanmegbecsüljék a mőbil állőmás sebességét. Következésképpen, a győrsabbés lassabb mőbil állőmásőkat könnyen meg lehet különböztetniegymástól, és egy hierarchikűs cellaszerkezetet hatékőnyan fel lehethasználni a kapacitás növelésére és a hívásátadásők csökkentésére egycellás kőmműnikációs rendszerben. ŕ
