Problems with the data in the side_info.txt file that records CSI information. #395

Closed petrichorZSY closed 5 months ago

petrichorZSY commented 6 months ago

As far as I know, every four lines in the side_info.txt file is a set of data, among which the CSI and equalizer data are the third and fourth lines. However, in the records we got, the data in the third and fourth lines are all 0, but when running CSI_rader The data graph drawn using python is not always 0. What's more, the waterfall chart is different from your demo video on bilibili. Our waterfall chart does not change significantly when there is occlusion. I would like to ask Dr. Jiao to answer my questions, please.
