A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication
ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.

SINR for DS-CDMA with random spreading [PDF]
For wireless multipath fading channels, the performance of a direct-sequence code-division multiple-access (DS-CDMA) system is degraded by interference, including multipath interference (MPI) and multiuser interference (MUI). For the downlink DS-CDMA with random spreading, we derive the variances of MPI and MUI and obtain the signal-to-interference ...

This study developed a stepwise electrolysis process that converts photovoltaic silicon waste into high‐value silicon anode materials, transforming sheet‐like silicon waste into silicon nanowires. The method enhances resource utilization efficiency and offers a promising approach for developing high‐performance Li‐ion battery anodes.

Dynamic Resource Allocation for LEO Satellite Systems Under Heterogeneous Traffic Distributions
ABSTRACT This paper proposes an efficient resource allocation scheme for low Earth orbit (LEO) satellite systems. Taking into account the unique characteristics of LEO systems for 6G communication services, we introduce a dynamic bandwidth and power allocation scheme specifically designed to accommodate highly heterogeneous traffic distributions.

SINR Maximizing Beamforming Schemes for the Full Duplex Amplify-and-Forward Relay Channel
We propose signal-to-interference-plus-noise power ratio (SINR) maximizing rank one beamforming schemes for the full-duplex (FD) relay systems. The non-regenerative amplify and forward (AaF) relay is considered with multiple transmit antennas and ...

Multi-Broadcasting under the SINR Model
We study the multi-broadcast problem in multi-hop wireless networks under the SINR model deployed in the 2D Euclidean plane. In multi-broadcast, there are $k$ initial rumours, potentially belonging to different nodes, that must be forwarded to all $n$ nodes of the network.

The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.
