Patent ID: 11871233
Assignee: TRUSTEES OF DARTMOUTH COLLEGE
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 19:
20. The method of claim 12, wherein the wireless signal is transmitted from a transmitter, and wherein the difference of phase and amplitude of the repeating portion is a first difference of phase and amplitude of the repeating portion, the method further comprising:
responsive to the first difference of phase and amplitude of the repeating portion being greater than a threshold, communicating with a trusted communication device to determine whether the trusted communication device is located at or greater than a predetermined distance apart from the single-antenna device;
responsive to determining that the trusted communication device is located at or greater than the predetermined distance apart from the single-antenna device, requesting the trusted communication device to:
receive, from the transmitter, the wireless signal;
determine a second difference of phase and amplitude of the repeating portion; and
compare the second difference to the threshold; and
responsive to receiving a response from the trusted communication device indicating that the second difference is greater than the threshold, determining that the wireless signal is transmitted from an adversary.
