RF is noise.

A microprocessor can do wonderful things extracting signal from noise but its all hard mathematical stuff.

Maybe a sufficient place to start is using an oversampling voting frame system.

Back in '85 we took a standard audio channel into a zero-crossing detectors and into a microprocessors interrupt line. We piped a lot of information through that channel over a city wide network.

Of course it hd some idiocy in the design. Before I got there, the engineer that did the original board put the interrupt on a non-maskable highest priority interrupt... making us jump through some hoops to handle high frequency white noise when no one was transmitting. Argh! An example of a hardware engineer trying to do microprocessors without understanding them. I had to have a small filter added so we didn't get the micro constantly interrupted without recourse.

Oh well, that's about all I can say on that project.
