Regarding plotting complex CSI values as Empirical pdf

[Vyomax]

This code provide great help in my ongoing dissertation project of CSI based localisation
I'm trying to generate location based identity without using phase information. (Inspired by "spot localisation using PHY layer information" http://research.microsoft.com/apps/pubs/default.aspx?id=160806 )

i'm in trouble in getting empirical pdf of individual sub-carrier's complex value..

Kindly will you help me to short out the problem i'm facing??

I'm attaching the image of the plot i requires..
plotting direct absolute value is easy but can not get the second plot...

Thanks

If you want to utilize phase information, the phase in raw CSI need to be calibrated in order to cancel random offset caused by asynchronous between transmitter and receiver. The method of phase calibration is introduced in the paper you refer to me(sec 4.1).

Thank you for your sharing, I am very interested in your project, you have the detail of the project or the introduction of engineering realization way?I didn't find the ”.mat“ files in the matlab code. No upload CSI test data?I hope very much to your reply thank you very much.

@huangl111 thank you for your shaing ,and I want to konw how to process the raw CSI in real-time?
