How does digital TV broadcast prevent ghosting effects?

Good morning world!

I've been reading about the new digital TV standards (8-VSB, DVB-T,
ISDB-T) and they all mention that the standards are more robust
compared to the analog standard. For example, all state that
practically ghosting effects are eliminated with DVB-T and ISDB-T
providing more robust response to mulitpath effects than 8-VSB.

How do these standards eliminate ghosting effects?

I also read a similar scheme for analog TV using Ghost Canceling
Reference (GCR) signals from both transmitter and receiver. Is this
pretty much the same idea?

Thanks!
