Abstract

Det er beskrevet en fremgangsmåte og et system for hur- tig og støyfri datakommunikasjon via energiforsynings- nett på hvilket som helst spenningsplan. Den kombinerte virkning av forstyrrelser på grunn av signalforvreng- ning, frekvensselektiv signalsvekkelse eller -støy og ved pulsforstyrrelser, reduseres ved anvendelse av en MCM-flerbærermodulasjonsmetode. Ved kombinasjon av MCM- metoden med en spesiell adaptert innfeller (data- forvrenger) og en feilbeskyttelseskoding, kan feilrater Ut reduseres drastisk og overføringshastigheter økes tyde- lig over 2 kbit/s.
