Deep CSI Feedback for FDD Massive MIMO Systems: A Curvelet Learning Approach
Mengli Tao, Jiancun Fan, Huiqiang Xie +1
Downlink channel state information (CSI) feedback plays a key role in frequency division duplex (FDD) massive multiple-input multiple-output (mMIMO) systems. The growth of antennas…
Coarse-to-Fine Semantic Communication Systems for Text Transmission
Mengli Tao, Jiancun Fan, Jie Luo +1
Achieving more powerful semantic representations and semantic understanding is one of the key problems in improving the performance of semantic communication systems. This work foc…
Semantic MIMO Systems for Speech-to-Text Transmission
Zhenzi Weng, Zhijin Qin, Huiqiang Xie +2
Semantic communications have been utilized to execute numerous intelligent tasks by transmitting task-related semantic information instead of bits. In this article, we propose a se…
Hybrid Digital-Analog Semantic Communications
Huiqiang Xie, Zhijin Qin, Zhu Han +1
Digital and analog semantic communications (SemCom) face inherent limitations such as data security concerns in analog SemCom, as well as leveling-off and cliff-edge effects in dig…
