Mobile Communications in Intelligent Rail Transit: From LCX to PASS
Yiran Guo, Wei Chen, Cong Yu +3
Wireless communications in intelligent rail transit face harsh propagation conditions, including severe penetration loss, frequent blockages, and amplified large-scale fading. Exis…
Uplink Assisted Joint Channel Estimation and CSI Feedback: An Approach Based on Deep Joint Source-Channel Coding
Yiran Guo, Wei Chen, Bo Ai
In frequency division duplex (FDD) multiple-input multiple-output (MIMO) wireless communication systems, the acquisition of downlink channel state information (CSI) is essential fo…
Joint CSI Estimation-Feedback-Precoding via DJSCC for MU-MIMO OFDM Systems
Yiran Guo, Wei Chen, Bo Ai +1
As the number of antennas in frequency-division duplex (FDD) multiple-input multiple-output (MIMO) systems increases, acquiring channel state information (CSI) becomes increasingly…
Deep Learning for CSI Feedback: One-Sided Model and Joint Multi-Module Learning Perspectives
Yiran Guo, Wei Chen, Feifei Sun +3
The use of deep learning (DL) for channel state information (CSI) feedback has garnered widespread attention across academia and industry. The mainstream DL architectures, e.g., Cs…
