  abstract =      {A single-antenna device includes a single antenna, at least one processor, and at least one memory. The single-antenna device is operable to receive a signal including at least one frame. Each of said frame includes a repeating portion. The single-antenna device determines a difference of phase and amplitude of the repeating portion and further determines whether the signal is transmitted from a trusted source based at least in part on the difference of phase and amplitude of the repeating portion.},
