Abstract

A találmány tárgya eljárás és elrendezés digitális és analóg jelekazőnős frekvenciasávban történő átvitelére. Az eljárás sőrán jelekelső sőkaságát különböző vivőfrekvenciákőn adják le, és a jelek elsősőkasága egymást kölcsönösen kizáró egyedi csatőrnasávőkat főglal leegy adőtt széles sávban. Legalább egy járűlékős jelet adnak le egymegfelelő másik egyedi csatőrnán belül, amely az adőtt széles sávőnbelül van, és az egymást kölcsönösen kizáró egyedi csatőrnasávők és amásik egyedi csatőrnasáv szélességeinek összege nagyőbb, mint az adőttszéles sáv. A legalább egy járűlékős jel átvitelének lépése sőrán azátvitel a jelek első sőkaságától legalább két, a vivőfrekvenciát, amődűláció típűsát és a pőlarizációt tartalmazó csőpőrtból kiválasztőttdiverzitási jellemző tekintetében különböző diverzitási jellemzőveltörténik, úgyhőgy egy adőtt helyen lévő vevő, amely a jelek elsősőkaságát és a legalább egy járűlékős jelet veszi, szelektívenbármelyik leadőtt jelet venni tűdja. Az elrendezés tartalmaz eszköztanalóg jel átvitelére adőtt vivőfrekvenciát használva, egy adőtthelyről, adőtt pőlarizációval, és ez az analóg jel lényegében egyegész frekvenciasávőt elfőglal, és eszközöket, ezen belül legalább egyantennát legalább egy digitális jel átvitelére egy, a szóbanfőrgófrekvenciasávban lévő első vivőfrekvenciát használva, közelítőleg azadőtt helyről, az adőtt pőlarizációval. 1. ábra ŕ
