Time and frequency domain question about data decoded

[waywyany]

hello，I wonder what information samples['csi'] got? Is that data in the time domain? In one issue you said that CSI data is already in the frequency domain after the end of the chip acquisition process, may I ask if I want to get time domain information? Should I ifft samples['csi'] or decoder(device).unpack(samples['csi'])?
thanks a lot!!!

You should do ifft on decoder(device).unpack(samples['csi']).
