Open the CIPO recordAbstract From the Canadian patent
A vector generator generates one or more pseudo-random noise PN sequences as matched-filter , PN vectors for a matched-filter correlator of a code division multiple-access , (CDMA), demodulator. The period and clock of the local PN code sequence may be employed as a time, reference, and each matched-filter PN vector has a known code-phase offset with respect to the local, PN code sequence. Matched-filter PN vectors having a chip-length on the order of a data symbol, period, such as 64-chip sequences are generated within a short period of time compared to the period, of the local PN code sequence. A state of the local PN code sequence is periodically captured from the, local PN code …

Why it's free to use
- Filed August 18, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 18, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 18, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
