Abstract

Korreksjonsverdien av utbredelseskurven for hver forutbestemte orientering oppnås ut fra forskjellen mellom målte data for et mottatt signals kodeeffekt av et ønsket signal og utbredelseskurven. Utbredelseskurven korrigeres ved å bruke korreksjonsverdier og tilstanden av radiobølgeutbredelsen simuleres ved å bruke utbredelseskurven etter korreksjonen. Videre beregnes en relativ verdi på grunnlag av forskjellen mellom de beregnede verdier av det mottatte effekttetthetsforhold innen et bånd før og etter modifisering av radioparameterinnstillingene og den beregnede relative verdi legges til de målte data for det mottatte effekttetthetsforhold innen båndet, og det mottatte effekttetthetsforhold innen båndet estimeres etter modifisering av radioparameterinnstillingene.
