Abstract

Foreliggende oppfinnelse foreslår en fremgangsmåte for estimering av en signalvarians for et mottatt signal (y) overført via en transmisjonskanal, hvilke fremgangsmåte omfatter de trinn: å estimere energien (RSSI) i det mottatte signa- let (y), å estimere energien (Emax) i tapper for kanalimpulsrespons (h), og å esti- mer signalvariansen (VAR) for det mottatte signalet ved å subtrahere den esti- merte energien i kanalimpulsrespons-tapper (Emax) fra den estimerte energien (RSSI) i det mottatte signalet, slik at denne signalvariansen oppnås som VAR = RSSI - Emax. Foreliggende oppfinnelse foreslår også en tilsvarende tilpas- set anordning.
