Signal denoising and filtering #89

Open xiaokangkang6 opened 1 year ago

xiaokangkang6 commented 1 year ago

The original signal is very noisy. Could you please teach me how to filter it?

We discussed several denoising methods in "WiFi Sensing on the Edge: Signal Processing Techniques and Challenges for Real-World Systems" (https://www.people.vcu.edu/~ebulut/COMST22_WiFi_Sensing_Survey.pdf). We used the ESP32-CSI-Tool for all of the experiments in that paper. Good luck.
