A guy on the linkedin DSP group posted about "System Compression" as well, which is related to compressive sensing. I haven't looked into it at all, but here's the link:
https://www.linkedin.com/groups/144812/144812-6155834561751191554 In case you can't access that link, he doesn't give much info about how System Compression works, but he links variously to this stuff: http://qualvisual.net/Rapid.php https://arxiv.org/ftp/arxiv/papers/1311/1311.5831.pdf http://dsp.rice.edu/cs http://dsp.rice.edu/sites/dsp.rice.edu/files/cs/CSintro.pdf On Mon, Aug 22, 2016 at 10:06 AM, Alan Wolfe <alan.wo...@gmail.com> wrote: > Thanks for the info, very interesting!
