Abstract

En mottatt effekt til et kodedelt multippel aksess (eDMA) signal blir bestemt. Sampler til et spektrum assosiert med det mottatte eDMA signalet blir tatt som mottatte sampler (108), som så blir korrelert med en kode til eDMA signalet (110). For korrelerte sampler under en første terskel, vil disse korrelerte sampler bli prosessert som å være gjort til null. For sampler mellom den første terskelen og den andre terskelen (114) vil disse korrelerte sampler bli prosessert ved å omskalering (116). De korrelerte sampler over den andre terskelen går igjennom uforandret. Det mottatte effektnivået til det mottatte eDMA signalet blir så bestemt ved å bruke de korrelerte samplene etter prosesseringen.
