Abstract

SAMMENDRAG Stokastisk pulsing for å bruke vilkårlige eller pseudo-vilkårlige sekvenser blir anvendt til å bestemme kjernespinnegenskaper i grunnformasjoner. Dette reduserer kraftbehovene. Behandling av de mottatte signalene kan innbefatte lineær eller ikke-lineær krysskorrelasjon med eksiteringspuls-sekvensen. Invertering av resultatene av behandlingen gir den ønskede kjernespinn-egenskap.
