Webb29 juli 2024 · For example, to meet the target BER of 0.15 for a QPSK-modulated signal, the PNR is selected to be at most −8 dB when the SNR is 3 dB and the resulting success of covertness is 65%. Furthermore, we observe that the Gaussian noise based perturbation results in a lower BER than the adversarial perturbation in the low PNR regime.
