Abstract

Oppfinnelsen angår en fremgangsmåte for deteksjon av rammekvalitet og en mottaker for iverksettelse av fremgangsmåten. For deteksjon av rammekvalitet sammenlignes i fremgangsmåten resultater A og B (27 og 28) med hverandre og med en forutbestemt terskelverdi (241). Resultat A (27) dannes enten som sum- men/produktet av myke bit-avgjørelser, eller som bitfeilhyppigheten, fra datasku- rer som omfatter biter fra suksessive rammer N og N + 1. Resultat B (28) dannes på samme måte for rammene N -1 og N. Når resultatene A og B (27 og 28) sam- menlignes med hverandre, bestemmes det at ramme N er en dårlig ramme hvis et av resultatene (27 eller 28) er vesentlig lavere/mindre enn det andre resultatet (28 eller 27). Det bestemmes også at ramme N er en dårlig ramme dersom begge resultater (27 og 28) er lavere/mindre enn den forutbestemte terskelverdien (241). Fremgangsmåten forbedrer deteksjon av en dårlig ramme, og reduserer følgelig den interferenslyd som mottas av en mottaker og som forårsakes av feilaktig tol- kede dårlige rammer, særlig under stillhet.
