Abstract

Fremgangsmåte og system for å justere amplitude-og fasekarakteristikker av trådløse kommunikasjonssignaler, generert av en analog radiosender, basert på sendingseffektkontroll-(TPC) signaler mottatt av en basestasjon (BS) og kjente karakteristikker av en effektforsterker (PA) som inkluderes i senderen. En digital forforstyrrelseskompensasjonsmodul, som har real-og imaginærsignalveier, mottar og prosesserer real-og imaginærsignalkomponenter som brukes til å generere trådløst kommunikasjonssignal. Fase- og amplitudekarakteristikker av det trådløse kommunikasjonssignalet er kontrollert i responsen til TPC signalene, slik at svekkede amplitude- og fasekarakteristikkene av PA er korrigert.
