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...

Reliable reception in orthogonal frequencydivision multiplexing (OFDM)-based low-altitude communication networks remains challenging, as unmanned aerial vehicles may be exposed to rapidly time-varying and severe jamming. Although deep learning-based receivers such as DeepRx demonstrate strong robustness, their high com...

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...
