Low Complexity Neural Network Digital Predistortion of Wideband Power Amplifiers through Feature Selection

Collection of newly published wireless, signal-processing, and instrumentation research with several security-relevant findings. Key items: a low-complexity feature-selection neural-network DPD for wideband power amplifiers (public datasets released); multiple ISAC works (mode-selectable pinching antennas, DFT-p-FDMA chirp waveform, temporal artificial noise for dual-security in OFDM-ISAC) that propose both new capabilities and new attack/defense techniques (e.g., temporal AN to simultaneously frustrate eavesdroppers and malicious sensing); reconfigurable metasurfaces, 6D movable antennas (6DM
