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

Claim 8:
9. The non-transitory computer readable medium of claim 1, wherein the wireless signal is transmitted from a transmitter, wherein the difference of phase and amplitude of the repeating portion is a first difference of phase and amplitude of the repeating portion, and wherein, the instructions, when executed by said processor, cause said processor and the single antenna to:
responsive to the first difference of phase and amplitude of the repeating portion being greater than a threshold, communicate 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, request 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, determine that the wireless signal is transmitted from an adversary.
