Hi, I used transmitter system object "sdrtx('ZedBoard and FMCOMMS2/3/4')" to connect to ZedBoard and AD9361, and I already successfully transmitted the waveform.
However, now I would like to transmit the same waveform on the Simulink, and I used the SDR Transmitter block (also ZedBoard and FMCOMMS2/3/4 version) in Communication System Toolbox for Xilinx Zynq-Based Radio. I encountered serious underflow problem on Simulink, since I changed the baseband sampling rate to 30M Hz. But it works well on original script version (using tx.transmitRepeat function) even if I modify the baseband sampling rate.
What is the difference between these two version and how could I solve this problem on simulink? (Opening the Burst mode wouldn't work.)
Thank you very much.
