Extract Channel State Information from WiFi-enabled ESP32 Microcontroller. Active and Passive modes available. (https://stevenmhernandez.github.io/ESP32-CSI-Tool/)
Hi
I've been working on a project related to wifi-sensing and we're going to use esp32 in our project. As I've read articles so far, the CSI matrix should be a vector of complex numbers. I am wondering why the output of this toolkit on CSI only includes some real numbers? Where are the imaginaries? How can I calculate the amplitude and phase of the subcarriers?
I would be grateful if someone could explain it to me.
