Open the CIPO recordAbstract From the Canadian patent
The present invention discloses a method and system for interleaving blocks of a packet to minimize the effects of burst errors and at the same time enhance the effectiveness of the ARQ protocol. A packet is first divided into a plurality of blocks. Each block is then individually encoded and inner-block interleaved. Thereafter the blocks are interleaved over a longer time period. By performing two stages of interleaving the present invention allows for the , size of a packet block to be kept at a minimum which increases the , effectiveness of the ARQ protocol and provides greater interleaving of the packet's data elements so as to minimize the effects of burst errors.

Why it's free to use
- Filed March 26, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 26, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 26, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
