Fig. 4From: Identification and authentication for wireless transmission security based on RF-DNA fingerprintThe whole process of fingerprint generation. The whole RF-DNA fingerprint generation process including five steps: (1) four RF devices, (2) collect N=2000 samples, (3) divide one sample into NR=16 equal length sub-region, (4) calculate NF=3 features, and (5) extract NS=4 statistics featuresBack to article page
