Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for dynamically generating multiple level decision thresholds of an M-ary demodulated signal for decoding the signal. The threshold values, are obtained by obtaining the maximum and minimum peak values of the demodulated, M-ary signal, averaging these peak values and subsequently processing these averaged, values to establish the threshold for the particular M-ary signal. Infinite impulse response, filters may be advantageously used in the averaging process and these filters may be, preloaded with maximum and minimum peak values such that decision threshold levels, may be generated immediately after receiving the M-ary demodulated signal.

Why it's free to use
- Filed January 17, 2000 and granted April 1, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 17, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 17, 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.
