Open the CIPO recordAbstract From the Canadian patent
The invention is CDMA quadrature signal technology that controls the transmit power of a CDMA signal (302, 407). The CDMA quadrature signal technology receives a CDMA signal (302, 411), and in response process quadrature , components of the CDMA signal to generate a power control signal (517). The CDMA quadrature signal technology adjusts the gain of the CDMA signal (407) in response to the power control signal (517). A CDMA transmitter (301) transmits the CDMA signal after the gain is adjusted. One example of the CDMA transmitter is a CDMA base station (412). Using the invention a multi-sector , CDMA base station (412) can control power without transferring gain information to base …

Why it's free to use
- Filed March 10, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 10, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 10, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
