When I sense the timing is not right - i.e. their 
response is a bit too late, or early, I purposely only 
send a partial call.  If the station doesn't correct 
you, it's pretty certain he was calling someone else.

Example:  I am running split on 40m and DL6FBL calls 
me on 40m.  DL6FBL was loud and clear, but I only 
say "DL6? 59 03"  If DL6FBL doesn't correct his call, 
you can be pretty certain he was calling someone else. 

If there are no other clear RX frequencies, sometimes 
you might have to tough it out.  In those cases, I end 
up sending a lot of partial calls just to make certain 
the station is really calling me.  Sometimes I will 
try and change my CQ cycle to see if I can get out of 
synch with the other guy listening on the same RX 
which again helps identify the station that is calling 
you.
