Undervisning: Digital Kommunikasjon

Grunnleggende teori for kommunikasjonssystemer, både trådløst (radio) og kabelbasert.

Gir grunnleggende forståelse for hvordan man konstruerer et digital kommunikasjonssystem, hvordan digital informasjon (bits) blir formatert for å sendes over en kanal. Samplingsteori forklarer hvordan analog informasjon digitaliseres for overføring. Modulasjonsmetoder for som brukes i moderne kommunikasjonssystemer forklares og man ser hvordan dette brukes for å spare båndbredde, dvs mest mulig bits overført per Hz båndbredde. Videre studeres mottakerstrukturer og teori. Kurset forklarer også grunnleggende teori for feildetektering og feilretting som finnes i alle moderne kommunikasjonssystemer. Metoder for hvordan flere systemer deler samme kanal blir også gjennomgått. 

Etter kurset vil du ha en godt grunnlag for å forstå moderne kommunikasjonssystemer, da kurset forklarer de grunnleggende metodene og byggesteinene som brukes i de fleste standarder innen f.eks mobiltelefoni, WLAN, Bluetooth, og lignende.
