What is the mechanism for separating the wheat from the chaff?

If we have a continually full channel full of fulsome noise, how does the receiver
distinguish valid traffic from nothing? Are there false positive & false negative
rates at play here? Presumably both would have to be dialled down to be pretty low.

Which as we all know is pretty much impossible.
