Abstract

En radioforsterker for selektivt å forsterke for- skjellige tidsluker i et radiosignal som bærer synkro- nisasjonsdata, omfatter en radiomottager (1) for å motta innkommende radiosignaler; en mengde forsterkningsveier (2a, 2b) for å forsterke radiosignalene som mottas av radiomottageren; en bryteranordning (3) for selektivt å omkoble de innkommende radiosignalene til individuelle forsterkningsveier blant mengden av forsterkningsveier; en anordning (4) for å overvåke de innkommende radio- signalene; en datautskillings-anordning for, fra utgangen av overvåkningsanordningen, å utskille synkronisasjons- data båret av radiosignalene; og en styreanordning for å styre bryteranordningen (3) som svar på synkronisasjons- dataene utskilt av datautskillings-anordningen. Denne sammenstillingen tillater at omkoblingen styres av data som bæres av signalet, uten å dekode og rekode signalet som skal sendes, slik at forsinkelsen som skapes av slik koding/ dekoding, unngås.
