Livestreamcsi Save

#Ploting CSI in real-time These file are basically used to plot csi in real-time using MATLAB. You need some pre-knowledge about how to extract CSI.

decode_csi_matlab

The files under this folder are used to parse the CSI data using MATLAB. You can use them to see how the CSI data are wraped in the .dat file and transplant them into another language. Noted that the original version to decode CSI publish on github mainly use fuction "read_bfee", if you want to replace it with "read_bfee_m" written here, you will need all the files under this folder.

log_to_file

The files under this folder is to send the CSI data through a TCP channel. You need to compile it using gcc.

gcc log_to_file.c -o log 

You can then run

sudo ./log

to send the data to the TCP server. If you want to save the sent data at the same time. You can give the argument, like this:

sudo ./log save.dat

The port number is 1234 in this program. You can modify in the file or make it as an input argument. You can also modify the IP address in this file and send the CSI data to another computer or broadcast the CSI data to many computers.

##parse_code_matlab The files under this folder is the original ones to decode the CSI data. Since it use C language to decode the CSI data, it is much more efficient. If you want to use the "realtime_plot.m" under the "realtime plot" folder, you should place these files with "realtime_plot.m" in the same directory.

realtime plot

The file under this folder is a TCP server acceptint realtime CSI data. I just do some basics stuffs to decode the original CSI without any further process. You can do anything at your will. System prototype like CARM, Ubicarse, WiGest, Spotify, etc can be implemented based on this.

Steps to plot csi data in realtime

• step 1 : complie the log_to_file.c

gcc log_to_file.c -o log

Place this file under "netlink" folder.

• step2 : place the files under "realtime plot" and "parse_code_matlab" in the same directory. This directory can be anywhere on your hard disk.
• step3 : run You should first run the server code. That is, excute "realtime_plot.m" first. Then run the log program "sudo ./log". If it is ok, you can see some print logs like "connect is ok". Noted that the basic steps to enable CSI can be done before or after these steps.
