I wonder if the required dynamic range won't be a large problem. What are your thoughts on this?

Maybe not in one wearable, but connect enough of them together and you might get there. We plan to do just that (with around 100 LARTs); in fact the LART was specifically developed for software radio. JDB [the StrongARM is even faster at fixed point FFTs than SHARC DSPs] -- LART. 250 MIPS under one Watt.
