Affine frequency division multiplexing (AFDM) has emerged as a competitive waveform for integrated sensing and communication (ISAC) in high-mobility scenarios, but its data-dependent high peak-to-average power ratio (PAPR) and ambiguity function (AF) sidelobes may degrade the power-amplifier efficiency as well as the s...

In wideband near-field multi-input multi-output (MIMO) systems, spherical-wave propagation induces a chirp-like channel structure, yet the intrinsic line-of-sight (LoS) element-wise transmit–receive coupling structure is usually neglected for improving channel estimation and localization accuracy, and the non-line-of-s...

Integrated sensing and communication (ISAC) has emerged as one promising candidate for 6 G wireless networks, yet it encounters difficulties in alleviating mutual interference in complex multi-user and multi-target scenarios. To address this issue, one feasible methodology is symbol-level precoding (SLP) that exploits...
A comprehensive end-to-end simulation framework that jointly models physical RIS antenna behavior and the complete signal processing chain is proposed, providing essential guidelines for the design and optimization of future wideband RIS-assisted systems.
