just starting to play with the tools now, but conceptually, isn't UWB like a bunch of receivers (ie: lots of "parallel software radios") ??

I know I'm doing a lot of hand waving here, but isn't it true to say you're either filtering out the channels in hardware (complex yes, impossible no) or you've got some monster DSP and an unobtanium ADC and you're doing it all in software.
