WebApr 9, 2024 · This paper proposes a semi-supervised learning approach for RF fingerprint recognition. This work directly uses the original I/Q sequence data, designs a fingerprint extractor based on the convolutional neural network (CNN), and uses K-means and DBSCAN algorithms to cluster the fingerprints. WebIQ = RF2IQ (RF,Fs,Fc) demodulates the radiofrequency ( RF) bandpass signals and returns the Inphase/Quadrature (I/Q) components. IQ is a complex whose real (imaginary) part contains the in-phase (quadrature) component. Fs is the sampling frequency of the RF signals (in Hz), Fc represents the center frequency (in Hz).
