Cramér-Rao Bound Minimization for Flexible Intelligent Metasurface-Enabled ISAC Systems
Qian Zhang, Yufei Zhao, Jiancheng An +4
Integrated sensing and communication (ISAC) have been widely recognized as a key enabler for future wireless networks, where the Cramér-Rao bound (CRB) plays a central role in quan…
Low-Complexity Channel Estimation for Internet of Vehicles AFDM Communications With Sparse Bayesian Learning
Xiangxiang Li, Haiyan Wang, Yao Ge +4
Affine frequency division multiplexing (AFDM) has been considered as a promising waveform to enable high-reliable connectivity in the internet of vehicles. However, accurate channe…
Multi-Resolution Codebook Design and Multiuser Interference Management for Discrete XL-RIS-Aided Near-Field MIMO Systems
Qian Zhang, Zheng Dong, Yao Ge +3
Extremely large-scale reconfigurable intelligent surface (XL-RIS) can effectively overcome severe fading and provide higher communication performance. However, current research on…
Multi-mode OAM Convergent Transmission with Co-divergent Angle Tailored by Airy Wavefront
Yufei Zhao, Ziyang Wang, Yilong Lu +1
Wireless backhaul offers a more cost-effective, time-efficient, and reconfigurable solution than wired backhaul to connect the edge-computing cells to the core network. As the amou…
Energy Efficiency of Rate-Splitting Multiple Access for Multibeam Satellite System
Jinyuan Liu, Yong Liang Guan, Yao Ge +2
Energy efficiency (EE) problem has become an important and major issue in satellite communications. In this paper, we study the beamforming design strategy to maximize the EE of ra…
New Complementary Sets with Low PAPR Property under Spectral Null Constraints
Yajing Zhou, Yang Yang, Zhengchun Zhou +3
Complementary set sequences (CSSs) are useful for dealing with the high peak-to-average power ratio (PAPR) problem in orthogonal frequency division multiplexing (OFDM) systems. In…
