Detecting Abrupt Change of Channel Covariance Matrix in IRS-Assisted Communication
Runnan Liu, Liang Liu, Yin Xu +3
The knowledge of channel covariance matrices is crucial to the design of intelligent reflecting surface (IRS) assisted communication. However, channel covariance matrices may chang…
Capacity-based Spatial Modulation Constellation and Pre-scaling Design
Xinghao Guo, Hanjiang Hong, Yin Xu +3
Spatial Modulation (SM) can utilize the index of the transmit antenna (TA) to transmit additional information. In this paper, to improve the performance of SM, a non-uniform conste…
RIS-Aided Receive Generalized Spatial Modulation Design with Reflecting Modulation
Xinghao Guo, Yin Xu, Hanjiang Hong +5
Spatial modulation (SM) transmits additional information bits by the selection of antennas. Generalized spatial modulation (GSM), as an advanced type of SM, can be divided into div…
CDDM: Channel Denoising Diffusion Models for Wireless Semantic Communications
Tong Wu, Zhiyong Chen, Dazhi He +4
Diffusion models (DM) can gradually learn to remove noise, which have been widely used in artificial intelligence generated content (AIGC) in recent years. The property of DM for e…
NB-IoT Uplink Synchronization by Change Point Detection of Phase Series in NTNs
Jiaqi Jiang, Yihang Huang, Yin Xu +3
Non-Terrestrial Networks (NTNs) are widely recognized as a potential solution to achieve ubiquitous connections of Narrow Bandwidth Internet of Things (NB-IoT). In order to adopt N…
