Ultra-High Resolution Method for Multipath Within a Co-Delay-Doppler Bin in DFT-P-OCDM

Communication systems can reuse their transmitted signals for sensing without dedicated radar transmissions. For an established DFT-preprocessed orthogonal chirp division multiplexing (DFT-P-OCDM) waveform, this task becomes difficult when several physical paths in a doubly selective channel fall into the same co-delay...

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...
