An Integrated Spectrogram Classifier-based Hand-Gesture Recognition SoC for an FMCW Radar Sensor

This work presents a system-on-chip (SoC) for FMCW radar signal processing to implement hand gesture recognition. For smart IoT device applications, a radar signal processing unit with a lightweight convolutional neural network (CNN) is integrated so that a spectrogram classifier can be implemented at the chip level. The spectrogram classifier is integrated with preprocessing blocks of FFTs and an...
