Accurate estimation of backscatter channels is crucial for enabling effective beamforming in multi-antenna readers. While full-duplex architectures improve the range of monostatic Backscatter Communication (BSC) systems, they remain highly vulnerable to jamming, which degrades channel estimation (CE) and transceiver pe...

Numerical results demonstrate that the proposed secure tri-hybrid beamforming design for DMA-aided ISAC improves the sensing SNR by approximately 3 dB compared to a tri-hybrid beamforming scheme with a fixed DMA electromagnetic design.

This paper proposes a computing-communication resource interchange method to enhance network availability (NA) in low-altitude heterogeneous networks (LA-HetNets). In these networks, communication resource conflicts and imbalances, caused by extreme heterogeneity (diverse mobility, mixed delays, and hybrid transmission...

Numerical results demonstrate that the proposed scheme achieves an effective time-quality tradeoff while maintaining the highest recovered secrecy; in a representative setup, it achieves gains of up to 3.6%, 15.7%, and 56% over the respective baseline schemes, with similar improvements under eavesdropper's channel unce...

In this paper, we consider the connectivity of a random network of N mobile devices in three dimensions (3D), where the location of each device or node has a Gaussian distribution in each dimension. For each pair of nodes, the probability of connectivity is related to the nodes'separation by a Gaussian connectivity fun...

This paper examines the power consumption (PC) efficiency of a mixed near- and far-field (MF) simultaneous wireless information and power transfer (SWIPT) system underpinned by a hybrid beamforming (HB)-based modular extra-large multiple-input-multiple output (XL-MIMO) array. Multiple information decoding (ID) and ener...
