The current invention relates to a method and a device for converting a random number sequence into carrier frequencies fx for mobile radio transmission. A shift register (25) with a register content of n bits is provided. The register content is shifted by 1 bit, whereupon a decision is made as to whether the value of a number of k bits of the register content is greater than the overall number Y of possible carrier frequencies fx whereby k is , less than or equal to n. If the decision is positive the value of the k bits , is used to select the next carrier frequency fx. The carrier frequency is selected, for instance, from a table in which the possible carrier frequencies are …

Why it's free to use
- Filed June 18, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 18, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 18, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
