Abstract

l et digitalt trådløst kommunikasjonsutstyr som har en feilkorreksjonsfunksjon blir linjekvaliteten raskt påvist samtidig som nøyaktigheten opprettholdes. Informasjon om bærebølge/støyeffekt-forholdet (C/N), hvor C/N for et mottatt signal brukes som et mål, konverteres til en feilpulsform for å generere en C/N/-feilpuls på grunnlag av hvilken linjekvalitet som overvåkes. En linjekvalitet hvis grad er slik at bitfeilraten (BER) blir noe forringet (10-10- 10-12) påvises raskt samtidig som nøyaktigheten opprettholdes.
