I think that you could implement this transmit waveform in a custom RFNoC block such that you would never have any issue with underruns. Although I don't use gnuradio myself, I believe that you could control your block easily from gnuradio. And, although this requires some FPGA programming, this would likely be a straightforward FPGA implementation. Rob
