Abstract

I et bredbåndet radiokommimikasjonssystem for datapakker kjermetegnet ved metoden for multitilgang med bærebølgeavlytting og drevet i et barskt frekvensanangement hvor båndbredden som opptas av modulerte sende/mottagningsbølger og modulasjonens sidelober er bredt mens frekvenskanalintervallet er smalt, er mottagningskarakteristikken for interferens fra nabokanaler blant en mengde terminaler som tilhører respektive celler og som befirmer seg i nærheten av nabofrekvens-cellegrenseområdet, forbedret. I indikatorsystemet for mottatt signalstyrke utføres smalbåndet kanalfilttering (med et smalbåndet båndpass- eller lavpassfilter som har et passbånd som er smalere erm båndbredden som opptas av en kanal), mens det i mottagnings/demodulasjonssystemet utføres bredbåndet kanalfilttering (med et bredbåndet båndpass- eller lavpassfilter som har et passbånd som er hk eller bredere erm båndbredden som opptas av en kanal).
