Open the CIPO recordAbstract From the Canadian patent
An improved system and method for maximum likelihood sequence detection is disclosed where an incoming stream of symbols subjected to intersymbol interference (ISI) are decoded without knowledge of channel coefficients. Through use of improved metrics, the Fano and stack algorithms may be employed to determine the maximum likelihood sequence detection for a given input data stream during blind equalization, offering improved performance over the Viterbi algorithm which requires foreknowledge of the channel coefficients to operate effectively.

Why it's free to use
- Filed September 3, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 3, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 3, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
