Abstract
Ved en fremgangsmåte og et system for utsending av informasjon, blir det benyttet bredbånds- frekvenssveip. Et visst sveip vil da angi et visst symbol. Ved den foretrukne utførelsesform blir fre- kvensene mellom hvilke sveipene opptrer, variert i henhold til et pseudo-tilfeldig oppsett. Videre vil en mottaker for effektiv detektering av slike bred- bånds-sveip omfatte referanseoscillatorer i for- skjellige mottaker-kanaler. Systemet har et meget godt utbytte hva angår datahastighet, tidsforsinkel- se, bruk av store kanal-båndbredder, liten sannsyn- lighet for detektering og liten risiko for tapping, samt god støyimmunitet.
