Abstract

Et kommunikasjonssystem ifølge foreliggende oppfinnelse omfatter en sender som kan betjenes for å kombinere en ortogonal Walsh-modulasjon med en minimal omtastings eller gaussisk, minimal omtastings bølgeform, for å danne et hybrid kommunikasjonssignal som bærer kommunikasjonsdata over en bølgeform med konstant amplitude som spres over tid og frekvens. Dette kommunikasjonssignal kan sendes til en RAKE-mottaker med flere korrelasjonsinnretninger, med avgitte vekter dannet for prosessering av dette hybride kommunikasjonssignal.
