Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for increasing system capacity in a mixed-rate wireless communication are disclosed. Improvements are obtained using multiuser, detection or antenna array processing techniques or both to explicitly cancel or attenuate, only the high power users. Multiuser detection may be combined with antenna array, processing to recover capacity appropriated by the high-power users. By mitigating the, interference effects of only the high-powered users the computational burden , is, manageable. An antenna array algorithm or a multiuser detection algorithm or both, are, applied only to n high rate users (n < k total users). In an antenna array processing, implementation, fewer …

Why it's free to use
- Filed June 22, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 22, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 22, 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.
