Physical Layer Security for MA-Aided SISO OFDM Systems Under Eavesdropper Location Uncertainty
This letter investigates physical layer security (PLS) in a movable-antenna (MA) aided single-input single-output (SISO) orthogonal frequency division multiplexing (OFDM) system, where the eavesdropper (Eve) is known only within a suspicious region and also optimizes its own MA positions. A closed-form artificial noise...
