wifi_csi_based_har's Issues

Dataset description

Hi @Retsediv,
Thank you for the great work.
I downloaded the data from this link, but I was unable to understand the data schema. Cloud you please provide some details about the meanings of rows and columns in each file?

ValueError: array must not contain infs or NaNs

greetings,
An error occurs every time train.py is run:
ValueError: array must not contain infs or NaNs

By the way,can you share the trained model?
Hope to hear from you soon

Modify the working antenna number

Hi Andrii,

Thanks for your amazing work regarding the WiFi CSI HAR. I have read your thesis and it helped a lot.

One question regarding the using of different numbers of the antenna. I am wondering how do you set the working antenna for transmitting and receiving? Can you force to set 3TX-3RX under 5G Hz. I noticed that when operating under different frequency mode, the antenna being used to sending/receiving the signal is automatically adjust by the firmware. When processing the CSI using Matlab, I found in some situation, the CSI matrix is 32 while some others are 22.

Thanks,
Simon
