Abstract

En krets (107) for måling av mottagningskvalitet måler mottagningskvaliteten for mottatte data avgitt fra en adderer (103). Når mottagningskvaliteten målt ved hjelp av denne krets er lavere enn en viss terskelverdi, avgir en krets (108) for regulering av sendeantennevekttall slike sendeantennevekttall W' til multipliserere (1061 - 106N), som ble lagret da mottagningskvaliteten siste gang overskred terskelverdien, i stedet for sendeantennevekttall W' avgitt fra en krets (105) for konvertering av antennevekttall.
