I find this attitude a little strange--not meaning to offend or anything. But this is, in fact *software* defined radio. So why is it always a big surprise when hardware types encounter an SDR platform and become more-than-vaguely-queasy at the though of having to, perhaps, learn a little bit about software. Just as not every piece of combinatorial logic that could ever be conceived of hasn't already been implemented in the (digital) hardware world, so to in the software world, not every conceivable functional block having to do with folding/spindling/mutilating a digital sample stream has yet been created (and, by extension, the useful combinations of those fundamental blocks). Which is why, well, those of us on either side of the fence (hardware or software) have jobs. Similarly, when a software-only guy encounters SDR, they become vaguely offended that they might actually have to think about (shock!) hardware issues, and real-time scheduling, and the vagaries of propagation. In the software world, you can just "add another layer of abstraction", to make your problems go away (or at least hide them under the covers sufficiently well that they're not so frightenting). But in a sense, SDR in general, and Gnu Radio in particular, are "perfect storms" for the uninitiated. You really, honestly, do have to *understand* things on both sides of the fence. And there aren't too many practitioners out there who straddle the fence acceptably well at this point. |
