Abstract
Fremgangsmåte og struktur for forbedret hastighet i en kvasistøykodeinnsamling. En mottaker kan omfatte trekk for å evaluere flere potensielle kvasistøy (PN)-digitale kodesekvenser parallelt for raskere innsamling av PN-koden som utnyttes av en tilsvarende sender. Flere PN-kodegeneratorer kan virke vesentlig parallelt idet hver er forhåndslastet for å generere en av et sett av mulige Gold-koder for skiftregisterets tapningskonfigurasjon. En av generatorene vil korrelere med sekvensen generert av senderen ved å overskride en bestemt korreleringsterskelverdi. Denne PN-kodesekvens kan identifiseres som den riktige PN-kodesekvens for dekoding av data mottatt på kommunikasjonsmediet tiltenkt den bestemte bruker ved å bruke PN-koden. Sammenlignet med gjeldende sekvensteknikker kan trekkene og aspektene herav raskere innsamle PN-digital kodesekvenser som utnyttes av en tilhørende overføring.
