Is it really a breach of causality if the output that displays the breach doesn't actually occur until some processing delay after the input that caused the output? I remember discussing this stuff

Most of my DSP work was in the early 70's using discrete chips. It was not even called DSP then. Built both FIT and IIR filters. At the time chips and DACs and ADCs were slow. That was OK as we were

If you want something simple to implement you can use what I did in the fldigi version of SCAMP: https://github.com/profdc9/fldigi/blob/master/src/scamp/scamp.cxx look at the int

Reg, my apologies, but I'm confused as to what you are trying to say. It looks to me as though you are discussing a standard Finite-Impulse-Response (FIR) filter, which can be thought of as a physical

Daniel, I am troubled by your assertion that one cannot determine an error probability unless both processes are Gaussian because the independence of random variables requires that p(x,y) =

FWIW My goal in this thread is to clearly state the mathematics. I taught myself compressive sensing in complete isolation. It took me 3 years of continuous effort in large part because I had no

Daniel, Is this correct? I saw no mention of it anything on the RFBitbanger that I read. Have Fun! Reg

Hi Reg, I believe there's still an OOK based submode of SCAMP included, not just the 2FSK. These links should go into more

As it is likely that most, if not all, list members have not read "A Mathematical Introduction to Compressive Sensing" by Foucart and Rauhut, I though it useful to provide a bit more detail. In the

I finally found my copy of Shannon. I've attached scans of 4 pages I think especially relevant to what I am proposing. The entire paper can be found online if you search on "bell system technical

Erik, Thanks for the video link. SCAMP is not decodable by ear or sent with a key. It's an RTTY protocol. Very cool, and really well suited to overnight message transfer at very low power levels.

Natural processes produce Gaussian noise. For the dit modulation one can choose any distribution one wishes. Consider that you have a 100 sample PRN that represents a dit at 12 wpm.There are 2^100

There is " dit" and "not dit". International Morse is defined in terms of those two primitives: fixed lengths of time on and off. If you modulate a carrier with a 1 kHz PRN sequence that will

https://github.com/OpenResearchInstitute/RFBitBanger-kit SCAMP is a mode that reminds of what it sounds like you're trying to accomplish here. Besides that there's Ebnaut, and WOLF - though those have

Any linear encoding/decoding method boils down to which subspace does the signal live in, and which does the noise live in. The extent of the overlap of the two determines the error probability. If
