I'm sending OFDM frames in a bursty manner, i.e., a have slots of 1 ms with
14 OFDM symbols.
These 1 ms slots are transmitted from time to time and I'm using SOB and
EOB to make it a busrty transmission.
What I have noticed is that some samples at the beginning of the slot are
being missed somehow. In order to solve it I had to pad 1000 zero IQ
samples to the beginning of the slot, only after that I started receiving
the slots correctly, however, now I have lots of "U" characters being
printed on the screen.
Is there some issue with the current UHD (host source or FPGA source) that
might be causing that problem?
I have tried with different UHD versions and the issue happen with all of
Could you guys, please, help me understand/solve this problem?
Many thanks and Kind Regards,
