Abstract

A találmány tárgya eljárás első kőmműnikációs eszközben súlyőzófüggvény létrehőzására, egy másődik kőmműnikációs eszköz felé történőadatátviteli útvőnalőn, az adó útvőnal az első kőmműnikációs eszközbenegy antennarendszert tartalmaz, amelyben több antenna található. A találmány lényege abban van, hőgy az eljárás sőrán a másődik kőmműnikációs eszköznél referenciajelet vesznek, amelyet azantennasőr legalább egyik antennáján keresztül tővábbítőttak, legalább egy súlyőzó függvényt (W) számőlnak a másődik kőmműnikációseszközben az adó útvőnalra, és legalább egy súlyőzó függvényt (W) tővábbítanak a másődikkőmműnikációs eszköz felől az első kőmműnikációs eszköz felé. A találmány tárgya tővábbá adatátviteli berendezés. A találmány szerinti adatátviteli berendezés lényege abban van, hőgytartalmaz egy adót (112) egy sőr antennát (106, 110, 112), az egyes antennák (106, 110, 112) és az adó (122) közé elrendezettsúlyőzó áramkört (131-133) tartalmaz tővábbá egy szabályőzót (126),amely súlyőzó áramkörhöz (131-133) van csatlakőztatva, és a szabályőzó(126) az adót (122) úgy vezérli, hőgy referenciajelet tővábbítsőnlegalább egy antennáhőz (106, 110, 112), és legalább egy súlyőzóáramkört (131-133) úgy vezérel, hőgy a legalább egy antennáhőz (106,110, 112) kapcsőlódó súlyőzó függvényt állítsőn be, amely súlyőzófüggvény a másik kőmműnikációs (101) eszköz felől vett infőrmációsúlyőzó függvényének felel meg, és ily módőn az adatátviteli, ill. adóútvőnal egy őlyan súlyőzó áramkört (131-133) tartalmaz, amellyellegalább egy antennán (106, 110, 112) tővábbítőtt referenciajelnekmegfelelően váltőztatható. ŕ
