The adoption of semantic communication in wireless systems introduces security challenges, as latent semantic features may leak sensitive information when intercepted. This paper proposes a secure semantic transmission framework based on semantic obfuscation and physical-layer keying. At the transmitter, semantic obfus...

Conventional line-shaped pinching-antenna systems (PASS) provide a flexible antenna architecture for highfrequency communications, but their one-dimensional deployment limits the spatial degrees of freedom available for multiuser beamforming. This paper investigates a multiuser downlink system enabled by two-dimensiona...

Orthogonal frequency division multiplexing (OFDM) is widely adopted in modern wireless communications, yet its performance is highly sensitive to carrier frequency offsets (CFOs), which destroy subcarrier orthogonality and introduce intercarrier interference (ICI). Although conventional ICI self-cancellation techniques...

Accurate jamming classification is essential for reliable orthogonal frequency division multiplexing (OFDM) systems, especially under low jamming-to-noise ratio (JNR) conditions where weak interference is difficult to detect. Existing approaches mainly rely on time-frequency representations (TFR), which discard phase i...

To exploit the full spatial degrees of freedom (DoFs) and maximize the average secrecy rate in unmanned aerial vehicle (UAV)-assisted communication systems, this paper proposes a novel physical layer security (PLS) architecture that integrates the UAV’s 3D kinematic trajectory with its tilt angle control. This joint de...

As one of the novel waveforms recently proposed for future wireless communications, affine frequency division multiplexing (AFDM) is capable of combating the effects of Doppler shifts and its superiority over the widely used orthogonal frequency division multiplexing (OFDM) in high-mobility scenarios has been demonstra...

Cyclic prefix (CP) is widely employed in orthogonal frequency division multiplexing (OFDM) systems, primarily due to its effectiveness in mitigating multipath interference and facilitating simplified receiver-side equalization. However, conventional CP-aided OFDM systems incur a loss in spectral efficiency, particularl...

Wideband time-division duplexing (TDD) massive multiple-input multiple-output (MIMO) precoding requires channel state information (CSI) that is both frequency-selective and temporally fresh. In practical fifth-generation New Radio networks, uplink sounding reference signal (SRS) resources are often sparsely allocated a...
