Fig. 2: Effect of jamming.

a Spectra and b eye diagrams measured by Bob, with and without the effect of jamming. In this example, the detuning Δν is 0.89 GHz, and Mallory broadcasts 10.7 dBm into Bob’s antenna side lobe, relative to Alice transmitted power of −10.5 dBm into the main antenna lobe. Mallory’s jamming introduces a wide interference component in the spectrum. In the time domain, the jamming asymmetrically affects the high bit as can be seen by comparing the histograms of data point distribution on the unjammed (top) and jammed (bottom) eye diagrams.
