Abstract

For å kunne bestemme en estimert verdi relatert til et informasjonsenhetskrav ved koding av et signal, tas et mål (nl(b)) for distribusjonen av energien i frekvensbåndet med i beregningen (102, 104, 106) så vel som den tillatte interferens i frekvensbåndet og energien i nevnte frekvensbånd. På denne måte oppnås et bedre estimat for informasjonsenhetskravet, slik at signalet kan kodes mer effektivt og presist.
