How to Extract CSI from Argos Open Dataset Files? #12

Closed xuanyv closed 3 months ago

xuanyv commented 3 months ago

Hello,

I am working with the Argos open dataset, specifically the file named ArgosCSI-8x4-2015-12-18-22-17-57_good_uhfstatic_vito_2omni_2directionalpolarized.hdf5. I would like to know the correct method to extract CSI (Channel State Information) from this dataset file.

So far, I have identified the following datasets within the file:

Could you please guide me on which dataset contains the CSI data and the steps required to correctly extract and interpret it?

Thank you for your help!

Of course!

We use the samps2csi function provided in the RENEWLab GitHub repository, specifically found on line 287 of the hdf5_lib.py file. This function allows you to extract the CSI (Channel State Information) from the raw data stored in the HDF5 format.

I hope this helps you!

Thank you very much for your answer. This function indeed can convert the raw HDF5 data into CSI, but how should parameters like polit_f and fft_size be obtained? I am new to this field and would greatly appreciate your guidance. If you could provide the processing code, that would be ideal.
