Method and apparatus for transmitting a signal at a predetermined level of reliability using retransmission of erroneously transmitted frames so as to minimize total transmission energy. The transmitting station evaluates the frame error rate (FER) as a function of energy. Next the transmitting station , determines a combination of initial transmission energies and retransmission energies that will provide the target level of reliability while minimizing the total transmission energy employed in the initial transmission and the retransmissions. The transmitting station transmits a frame with an initial transmission energy. Employing conventional feedback methods the transmitting …

Why it's free to use
- Filed October 7, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 7, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 7, 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.
