Center-Fed Pinching Antenna System for Uplink Environment Sensing
Cong Yu, Xu Gan, Bo Ai +3
A center-fed pinching antenna system (C-PASS)-enabled uplink environment sensing framework is proposed. Through the center-fed framework, doubled degrees of freedom is achieved com…
Deep Joint CSI Feedback and Multiuser Precoding for MIMO OFDM Systems
Yiran Guo, Wei Chen, Jialong Xu +2
The design of precoding plays a crucial role in achieving a high downlink sum-rate in multiuser multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OF…
Swin Transformer-Based CSI Feedback for Massive MIMO
Jiaming Cheng, Wei Chen, Jialong Xu +3
For massive multiple-input multiple-output systems in the frequency division duplex (FDD) mode, accurate downlink channel state information (CSI) is required at the base station (B…
Deep Joint Source Channel Coding With Attention Modules Over MIMO Channels
Weiran Jiang, Wei Chen, Bo Ai
In this paper, we propose two deep joint source and channel coding (DJSCC) structures with attention modules for the multi-input multi-output (MIMO) channel, including a serial str…
