Arrangement With Means for Ensuring Bona Fide of Received Signals

摘要

An arrangement including a receiver that receives a plurality of signals from different source that are modulated with a common carrier, where each signal of the signals experiences a transit delay and Doppler frequency shift before reaching the receiver. The receiver includes means, such as a directional antenna, to ensure that the received signals are bona fide, or at least not subject to the same bogus signal or signals to which a second receiver may be subjected. The arrangement further includes means for processing a signal derived from the signals received by the receiver with signals provided by a supplicant module to reach a conclusion about the bona fide of the signals provided by the supplicant module.
