I have modified ad9361-iiostream example so that I could transmit data samples from a file and write received data to another file. I transmit a frame 6 times in a loop and the result I get is attached. My settings are:
frequency- 5 GHz, BW- 20 MHz, sampling rate- 20MSam/s, AGC in fast attack mode.
When I took fft of the first frame received, I noticed a large dc component (figure attached). I know that AD9361 AXI core implements dc correction in receive chain. Is there anyway that I can suppress this dc component?
