Hi Xianda, |
if you don't use gnuradio, this might not be the right list for you...
Anyway, I think it's possible you're confusing something. start_of_burst / end_of burst are stream tags that are GNU Radio concepts. There is not something like this without GNU Radio.
UHD supports timed commands, which might be close to what you need, but I really don't understand what your question aims at.

Hi: Thank you so much for your kindly reply.I write c++ code use the uhd not gnuradio.So need I add start_of_burst at the beginning of every packet and add end_of_burst at the end of every packet?Thank you.

So, the OFDM code does *not* add EOB, but that doesn't matter if you have an up-to-date gr-uhd.
