A Spectrum-Efficient Cross-Layer RF Distance Bounding Scheme

The simulation results of the multipath signal identification. (a) The peaks that we obtained in multipath signal identification simulation. The three peaks in this graph correspond to one LOS signal and other two multipath signals, respectively. (b) The results of 50 simulations (). The average propagation delays correspond to the LOS signal and the multipath signals can be obtained by leveraging equation (15), where i is the average of abscissa values that correspond to the LOS peaks or the multipath peaks shown in this graph. In the simulations, the estimated average propagation delays of these three signals are 50 ns, 56 ns, and 70 ns.
