Is it really a reception issue, or more of a transmission issue?  Take
a look at the frequency characteristics of some of these different
waveforms, then look at your overall bandwidth of the signal you're
able to transmit as well as the overall bandwidth of your received
signal.

You may want to look at the Suggested Reading page on the wiki:

    http://gnuradio.org/trac/wiki/SuggestedReading

This will probably preemptively answer a lot of questions you have
with regards to radio communications.
