A dynamic combined power control and forward error correction control (FEC) technique for mobile radio systems which illustratively decreases tile power consumed by wireless transmitters and increases the number of simultaneous connections which may be supported thereby. Individual transmitter-receiver pairs may adaptively determine the minimal power and FEC required to satisfy specified quality-of-service (QOS) constraints. Specifically in accordance with an illustrative embodiment of the present invention a first, portion of a signal is encoded with a first code to generate a first encoded signal portion. Then the first encoded signal portion is transmitted with a first power level. Next …

Why it's free to use
- Filed January 28, 1997 and granted August 8, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 28, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 28, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
