Hi Markus, Well, the shortest possible pulse has duration 1/sampling rate and can be sent with 0…010…0 Now, that pulse has incredibly little power; and thus, the LO leakage and all negative effects will probably make that unnecessary hard to detect. I really recommend pulse compression: Can't

Dear list, I wonder how I could generate one single shortest possible pulse on my USRP2 with GNURadio.  Normally all the blocks would always generate an entire sequence, a continuous signal.  I want to generate (and analyze) the shortest possible signal.  Any ideas?  The background: I want to
