Introduction

testSpectrogram is an open-source platform for wireless channel simulation, human/hand pose extraction, gesture spectrogram generation, and real-time gesture recognition based on millimeter-wave passive sensing and communication systems.

Since this work is experiment-oriented, code might not be 100% consistent with our real implementation. But the gerneral core idea is the same. And we will keep making improvements and updating the code for clearer understanding.
