Open the CIPO recordAbstract From the Canadian patent
An innovative channelizer design methodology is provided to adjust the narrowband, channel frequency spacing and processing algorithm in order to develop a configurable, multi-rate channelizer (20) for multiple applications with different input data rates and input, channel group bandwidths. Given an input and output sampling rate and the input channel, group bandwidth, the input channel spacing the discrete Fourier transform , (DFT) size the, valid output DFT bins, the dead zone implementation including the number of samples to, blank for each chip, which exact samples to blank the timing error immunity , versus, performance degradation balance may be derived to design hardware …

Why it's free to use
- Filed May 9, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 9, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 9, 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.
