Open the CIPO recordAbstract From the Canadian patent
A transmittal signal is transmitted in a forward error correction format in casethe length of the transmittal signal satisfies prede termined conditions but not in a forward error correction format in case the length of the transmittal signal does not satisfy the predetermined conditions. Owing to this arrangement a long signal susceptible to errors, can be encoded in a forward error correction format. For transmitting a short transmittal signal wasteful consumption of transmission data capacity of a radio channel can be prevented.

Why it's free to use
- Filed April 30, 1996 and granted July 3, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 30, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 30, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
