Holographic Communication via Recordable and Reconfigurable Metasurface
Jinzhe Wang, Qinghua Guo, Xiaojun Yuan
Holographic surface based communication technologies are anticipated to play a significant role in the next generation of wireless networks. The existing reconfigurable holographic…
Joint Channel Sounding and Source-Channel Coding for MIMO-OFDM Systems: Deep Unified Encoding and Parallel Flow-Matching Decoding
Hao Jiang, Xiaojun Yuan, Qinghua Guo
In this work, we propose a deep unified (DU) encoder that embeds source information in a codeword that contains sufficient redundancy to handle both channel and source uncertaintie…
Blind MIMO Semantic Communication via Parallel Variational Diffusion: A Completely Pilot-Free Approach
Hao Jiang, Xiaojun Yuan, Yinuo Huang +1
In this paper, we propose a novel blind multi-input multi-output (MIMO) semantic communication (SC) framework named Blind-MIMOSC that consists of a deep joint source-channel coding…
Message Passing-Based Joint Channel Estimation and Signal Detection for OTFS with Superimposed Pilots
Fupeng Huang, Qinghua Guo, Youwen Zhang +1
Receivers with joint channel estimation and signal detection using superimposed pilots (SP) can achieve high transmission efficiency in orthogonal time frequency space (OTFS) syste…
