What about multipath?

What about it? It's a problem in every case.

Really?

Multipath is only a problem in analog systems where the information
is in phase differences, like an ILS system.

There is also the issue that ILS is AM and thus can't rely on
discriminator capture.

But I'm sure you know all about EM propagation theory, information
theory, and modulation theory.

All radio systems are analog. In fact, all physical systems are analog.
Multipath is a problem for all sorts of systems.
