Transpositional modulation communications

An aerial communication device comprising:

• a drone;
• a camera mounted on the drone;
• a signal repeater mounted on the drone and in communication with the camera, the signal repeater comprising:
• a signal receiver, and
• a signal transmitter,
• wherein the signal repeater is configured to perform operations comprising:
• receiving a first signal from a broadcast signal source, the first signal including a carrier signal modulated with a first modulation signal;
• receiving image data from the camera;
• encoding the image data in a second modulation signal;
• adding the second modulation signal to the carrier signal of the first signal to produce a combined signal, wherein the second modulation signal is a transpositional modulation (TM) signal and the first modulation signal is a non-TM signal;
• and
• transmitting the combined signal.
