Abstract

I et kommunikasjonssystem med radiostasjoner og fjerntliagende andre stasjoner, f.eks. et cellestrukturert mobilradiosystem, sender radiostasjonene ut radiosignaler og mottar radio- signaler, som i hvert tilfelle inne- holder informasjonssignaler. I henhold til foreliggende oppfinnelse kan sl mange som mulig av prosesseringsfunk- sjonene forskyves fra basestasjonene til de perifere stasjoner. Rad i os i gnålet som skal sendes ut av radiostasjonen (2) genereres ved at det i den fjernt- liggende perifere stasjon (10) frem- bringes en umodulert bærebølge og en bærebølge modulert med informasjonssig- nalet, og hvor bærebølgene avviker i frekvens med verdien på frekvensen til radiosi gnålet (f}). Disse to optiske bærebølger oversendes til radiostasjonen (2) og blandes der i en optisk mottager, slik at rad i os i gnålet som inneholder i n formasjonssignål et genereres. Et radiosignal som mottas i en radiostasjon (40) oversendes optisk til en fjernt- liggende innretning (44) og først der : blir den prosessert videre. Denne l ¿ oversendelse utføres ved at en optisk sender (41) som forefinnes i den fjerntliggende perifere stasjon (44) genererer en umodulert optisk bærebølge og sender den til en optisk modulator (43) som er lokalisert i radiostasjonen (40). I den optiske modulator (43) blir lyset, som er modulert med de mottatte radiosignaler, sendt tilbake og radio- signalet (f^) gjenvinnes ved optisk heterodyn-mottagelse av de umodulerte og modulerte bærebølger (Vg1, Vi1).
