I think a more fundamental issue is that "carrier sense" isn't actually 
defined in any kind of general way.  Certainly for *some* types of
  PHYs, you can do simple energy-presence detection.  But usually, it's 
more complicated than that, and it varies widely from PHY to
  PHY.  In some, you'll need to run a correlator before you even know 
whether the channel is busy or not.  In others, simple energy
  detection works.

I don't think there's a general-purpose way of doing this, but that's 
just my POV.
