Decentralized Hybrid Precoding for Massive MU-MIMO ISAC
Jun Zhu, Yin Xu, Dazhi He +3
Integrated sensing and communication (ISAC) is a very promising technology designed to provide both high rate communication capabilities and sensing capabilities. However, in Massi…
Two Birds with One Stone: Multi-Task Semantic Communications Systems over Relay Channel
Yujie Cao, Tong Wu, Zhiyong Chen +3
In this paper, we propose a novel multi-task, multi-link relay semantic communications (MTML-RSC) scheme that enables the destination node to simultaneously perform image reconstru…
Soft-Output Fast Successive-Cancellation List Decoder for Polar Codes
Li Shen, Yongpeng Wu, Yin Xu +3
The soft-output successive cancellation list (SOSCL) decoder provides a methodology for estimating the a-posteriori probability log-likelihood ratios by only leveraging the convent…
Fluid Antenna Grouping Index Modulation Design for MIMO Systems
Xinghao Guo, Yin Xu, Dazhi He +3
Index modulation (IM) significantly enhances the spectral efficiency of fluid antennas (FAs) enabled multiple-input multiple-output (MIMO) systems, which is named FA-IM. However, d…
GLDPC-PC Codes for MIMO Systems with Iterative Detection and Decoding
Binghui Shi, Yongpeng Wu, Yin Xu +3
In this work, we propose the integration of GLDPC codes with short polar-like component codes, termed GLDPC codes with polar component codes (GLDPC-PC). This approach leverages the…
GLDPC-PC Codes: Channel Coding Towards 6G Communications
Li Shen, Yongpeng Wu, Yin Xu +3
The sixth generation (6G) wireless communication system will improve the key technical indicators by one to two orders of magnitude, and come with some new features. As a crucial t…
