A Gradient Meta-Learning Joint Optimization for Beamforming and Antenna Position in Pinching-Antenna Systems
Kang Zhou, Weixi Zhou, Donghong Cai +4
In this paper, we consider a novel optimization design for multi-waveguide pinching-antenna systems, aiming to maximize the weighted sum rate (WSR) by jointly optimizing beamformin…
Improved ALOHA-based URA with Index Modulation: Efficient Decoding and Analysis
Linjie Yang, Pingzhi Fan, Zhiguo Ding +1
In this paper, an improved ALOHA-based unsourced random access (URA) scheme is proposed in MIMO channels. The channel coherent interval is divided into multiple sub-slots and each…
Open Set RF Fingerprinting Identification: A Joint Prediction and Siamese Comparison Framework
Donghong Cai, Jiahao Shan, Ning Gao +4
Radio Frequency Fingerprinting Identification (RFFI) is a lightweight physical layer identity authentication technique. It identifies the radio-frequency device by analyzing the si…
