Open the CIPO recordAbstract From the Canadian patent
A parallel punctured convolutional encoder (44) that provides convolutional coding, of a stream of digital data bits in a parallel manner for high frequency transmission. The, parallel convolutional encoder (44) includes a plurality of one-bit delay devices (46-56), and four XOR gates (78-84). Three consecutive bits are applied to the convolutional, encoder (44) in a parallel manner and four polynomial expressions are provided from the, XOR gates 78-84 in a parallel manner at each clock cycle where certain values , in the, polynomial expressions are provided and certain values are not provided to conform with, a particular puncture scheme of a desirable convolutional rate. In an …

Why it's free to use
- Filed June 26, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 26, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 26, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
