Fig. 8From: Amplify-and-forward relay identification using joint Tx/Rx I/Q imbalance-based device fingerprintingDetection probabilities comparison between suboptimal and non-optimal signal design and the corresponding upper bounds. The two compared relays have (αrx,θrx,αtx,θtx)=(− 0.03,3°,0.03,3°), (αrx,θrx,αtx,θtx)=(0.02,5°,− 0.05,− 4°), SNR =16 dB, N=14Back to article page
