I am keeping my implementation private while I look for commercialization opportunities, but I hope to open-source it later whether I'm successful or not. I will...
Interesting, thanks for sharing. I am curious, is there some reason I don't see larger FFTs used in RF communication?For example, it seems like encoding data in...
I've been looking into predictive maintenance, where accelerometers listen for e.g. bearing wear on various spinning machinery. It seems like a good application:...
Thanks! sin and cos are often implemented on a computer with polynomial approximations (to machine precision). The LFT is closely related to this approach.
This is in fact how the LFT came to be. I was using it to generate STFTs of many different power-of-2 window lengths (from property 6.) to find the best sparse approximations...
Preamble and NBIoT are interesting. Does "flooded with registers" mean your FPGA wasn't big enough to hold all the accumulators/mixers?I ran a test on 48 bins from...
50% is still a large fraction of the output. The LFT becomes helpful when you want to keep < 10% of the output (smaller the better). I think in your case computing...
