Open the CIPO recordAbstract From the Canadian patent
The adaptive bidirectional equalization process of the present invention first determines the point of lowest signal quality for the time slot being processed. Detection is then performed on the time slot in both directions until the processing meets at the point of lowest signal quality. This process reduces the bit error rate as compared to performing standard equalization on the time slot.

Why it's free to use
- Filed February 3, 1993 and granted February 23, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 3, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 3, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
