Abstract

Oppfinnelsen angår en fremgangsmåte for signaldeteksjon i en mottaker i et digitalt, celledelt nettverk. En kombinasjon av et ønsket nyttesignal og minst ett interfererende nabokanal-signal som kommer fra en kanal som ligger tilstøtende til en ønsket kanal, mottas på den ønskede kanalen, l samsvar med oppfinnelsen bestemmer man sammen kanalestimater for nyttesignalet og minst ett nabokanal- signal. Estimeringen utføres enten ved bruk av refc ansedeler, f.eks. en trenings- sekvens, som er kjent for mottakeren, eller ved å bruke symbol- eller bit- avgjørelser som frembringes ved avgjørelses-tilbakekopling. Så detekteres nytte- signalet ved å utnytte kanalestimatene for både nyttesignalet og nabokanal- signalet. Estimeringen kan også utføres separat, i parallell eller sekvensielt, i hvil- ket tilfelle et rekonstruert interfererende signal blir redusert fra nyttesignalet før deteksjonen.The invention relates to a method for signal detection in a receiver in a digital cellular network. A combination of a desired utility signal and at least one interfering neighbor channel signal coming from a channel adjacent to a desired channel is received on the desired channel, in accordance with the invention, channel estimates for the utility signal and at least one neighbor channel signal are determined. The estimation is performed either using refc parts, e.g. a training sequence known to the recipient, or using symbol or bit decisions produced by decision feedback. Then the utility signal is detected by utilizing the channel estimates for both the utility signal and the neighboring channel signal. The estimation can also be performed separately, in parallel or sequentially, in which case a reconstructed interfering signal is reduced from the utility signal before detection.
