Dear All, 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 them: - UHD_003.009.005-0-unknown - UHD_003.010.002.000-3-g122bfae1 - UHD_4.0.0.rfnoc-devel-369-g1908672f Could you guys, please, help me understand/solve this problem? Many thanks and Kind Regards, Felipe Augusto
