Abstract
En fremgangsmåte og apparat for å prosessere flere trådløse kommunikasjonstjenester i en mottaker er fremlagt. En mottaker mottar mer enn én trådløs kommunikasjonstjeneste samtidig via et trådløst grensesnitt. Hver tjeneste blir sendt via et forskjellig bærebølgefrekvensbånd. Flere mottatte bærebølgesignaler blir nedkonvertert til et mellomliggende frekvens (IF) bånd ved å bruke en mikser og en lokal oscillator (LO). LO og samplingsfrekvenser blir justert slik at de konverterte IF båndsignalene til inngangssignalene er spektralt tilstøtende eller overlappende med hverandre til en viss grad. SINAD til tjenestene blir målt i hver av flertallet av spektralt overlappende betingelser. LO frekvensene og samplingsfrekvensen blir så justert basert på SINAD måleresultatene.A method and apparatus for processing multiple wireless communication services in a receiver is provided. A receiver receives more than one wireless communication service at the same time through a wireless interface. Each service is transmitted via a different carrier frequency band. Several received carrier signals are downconverted to an intermediate frequency (IF) band using a mixer and a local oscillator (LO). LO and sampling frequencies are adjusted so that the converted IF band signals to the input signals are spectrally adjacent or overlapping with each other to some degree. The SINAD of the services is measured in each of the majority of spectrally overlapping conditions. The LO frequencies and the sampling frequency are then adjusted based on the SINAD measurement results.
