Abstract

2005 -11- 0 3 24 En fremgangsmåte og nedhuls telemetriutstyr som anvender diskret flertonemodulasjon og adaptiv utfiltrering. Dette nedhulls telemetriutstyr inkluderer en nedhullssender, en kabel og en overflatemottaker koplet til nedhulissenderen gjennom kabelen. Overflatemottakere filtrerer adaptivt ut støy fra et signal som mottas fra nedhulissenderen. Denne fremgangsmåte inkluderer mottak av et tidsdomenesignal som fremfører ønsket informasjon ved spesifikke frekvenser samt adaptiv utfiltrering av i det minste en viss andel av støyen fra tidsdomenesignalet. Dette tidsdomenesignal inkluderer støy. Denne fremgangsmåte kan også inkludere forsinkelse av tidsdomenesignalet med en viss forsinkelsestid for derved å danne et forsinket tidsdomenesignal, samt adaptiv utfiltrering av i det minste en viss andel av den periodiske støy fra tidsdomenesignalet ved bruk av det forsinkede tidsdomenesignal. Denne fremgangsmåte kan også inkludere mottak av et referansesignal fra hver av én eller flere sensorer som er plassert for å motta en anvisning om en viss komponent av støyen, samt adaptiv utfiltrering av i det minste av en viss andel av hver støykomponent fra tidsdomenesignalet ved bruk av i det minste referansesignalet fra én av de én eller flere sensorer.
