Optimized Joint Relay and Antenna Selection for Enhanced Full‐Duplex Relay Networks
This study proposes a joint relay and antenna selection strategy for full‐duplex amplify‐and‐forward relay networks. By adaptively optimizing transmitter–receiver configurations based on channel conditions, the method reduces self‐interference, lowers outage probability, and symbol error rate, and enhances spectral efficiency, offering a scalable ...

CNN‐DDQN Spatial Learning for Fractional Frequency Reuse Optimization in 5G Heterogeneous Networks
This study proposes a spatially aware DRL framework that uses multichannel network‐state tensors and a lightweight CNN‐DDQN architecture to capture interference patterns and user clustering in 5G heterogeneous networks (HetNets). The model is computationally efficient with only 7361 trainable parameters, achieving 115× faster execution and < 10 ms ...

Optically Transparent Ka‐Band Absorber With Multi‐Fractal Rings and a Metal Mesh Ground Plane
ABSTRACT An optically transparent absorber based on multi‐fractal ring resonators and a metal mesh ground plane is presented for Ka‐band applications. By merging multiple resonances, the proposed absorber maintains an absorption bandwidth from 25.8 to 31.1 GHz.

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.
