Fig. 4From: Generative adversarial network-based rogue device identification using differential constellation trace figureD(x) of some pairs of recognized devices (blue bars) and rogue devices (red bars). The distribution of D(x) of some devices is shown in this figure. The blue bar in each sub-figure represents a recognized device and the red bar represents a rogue device for comparison. The abscissa indicates the value of D(x) and the ordinate indicates the frequency of occurrence of each value. The data is collected in a 30dB environment and the discriminator is trained for 5 epochs. The recognized and rogue devices were randomly selected from 54 devicesBack to article page
