Abstract
A communications system and methods for covert communications are provided. A first transmitter that transmits an information carrying signal to a target receiver, a second transmitter and a third transmitter transmit jamming signals to the target receiver, such that the information carrying signals and the jamming signals are interleaved when received by the target receiver The information carrying signals and the jamming signals can be at least partially overlapping by an eavesdropper.
Claims16
A communications system for covert communications, the communications system comprising:
- a first transmitter that transmits an information carrying signal to a target receiver;
- a second transmitter that transmits a first jamming signal to the target receiver, the second transmitter positioned at a first predetermined distance from the first transmitter;
- and
- a third transmitter that transmits a second jamming signal to the target receiver, the second transmitter positioned at a second predetermined distance from the first transmitter,
- wherein the first transmitter, the second transmitter and the third transmitter each transmit their respective information carrying signal, first jamming signal and second jamming signal such that the information carrying signal, first jamming signal and second jamming signal are interleaved when received by the target receiver.
A method for covert communications, the method comprising:
- transmitting, via a first transmitter, an information carrying signal to a target receiver;
- transmitting, via a second transmitter, a first jamming signal to the target receiver, the second transmitter positioned at a first predetermined distance from the first transmitter;
- and
- transmitting, via a third transmitter, a second jamming signal to the target receiver, the second transmitter positioned at a second predetermined distance from the first transmitter,
- wherein the first transmitter, the second transmitter and the third transmitter each transmit their respective information carrying signal, first jamming signal and second jamming signal such that the information carrying signal, first jamming signal and second jamming signal are interleaved when received by the target receiver.
