Semantic Communications: Principles and Challenges
Zhijin Qin, Xiaoming Tao, Jianhua Lu +2
Semantic communication, regarded as the breakthrough beyond the Shannon paradigm, aims at the successful transmission of semantic information conveyed by the source rather than the…
Perceptual Image Restoration with High-Quality Priori and Degradation Learning
Chaoyi Han, Yiping Duan, Xiaoming Tao +1
Perceptual image restoration seeks for high-fidelity images that most likely degrade to given images. For better visual quality, previous work proposed to search for solutions with…
Category-Adaptive Domain Adaptation for Semantic Segmentation
Zhiming Wang, Yantian Luo, Danlan Huang +2
Unsupervised domain adaptation (UDA) becomes more and more popular in tackling real-world problems without ground truth of the target domain. Though tedious annotation work is not…
Delay Characterization of Mobile Edge Computing for 6G Time-Sensitive Services
Jianyu Cao, Wei Feng, Ning Ge +1
Time-sensitive services (TSSs) have been widely envisioned for future sixth generation (6G) wireless communication networks. Due to its inherent low-latency advantage, mobile edge…
Exploiting the Shipping Lane Information for Energy-Efficient Maritime Communications
Te Wei, Wei Feng, Jue Wang +2
Energy efficiency is a crucial issue for maritime communications, due to the limitation of geographically available base station sites. Different from previous studies, we promote…
Hybrid Satellite-Terrestrial Communication Networks for the Maritime Internet of Things: Key Technologies, Opportunities, and Challenges
Te Wei, Wei Feng, Yunfei Chen +3
With the rapid development of marine activities, there has been an increasing number of maritime mobile terminals, as well as a growing demand for high-speed and ultra-reliable mar…
LDPC-Based Code Hopping for Gaussian Wiretap Channel With Limited Feedback
Zhao Chen, Liuguo Yin, Jianhua Lu
This paper presents a scheme named code hopping (CodeHop) for gaussian wiretap channels based on nonsystematic low-density parity-check (LDPC) codes. Different from traditional com…
When mmWave Communications Meet Network Densification: A Scalable Interference Coordination Perspective
Wei Feng, Yanmin Wang, Dengsheng Lin +3
The millimeter-wave (mmWave) communication is envisioned to provide orders of magnitude capacity improvement. However, it is challenging to realize a sufficient link margin due to…
Approximate Message Passing with Nearest Neighbor Sparsity Pattern Learning
Xiangming Meng, Sheng Wu, Linling Kuang +3
We consider the problem of recovering clustered sparse signals with no prior knowledge of the sparsity pattern. Beyond simple sparsity, signals of interest often exhibits an underl…
Message-Passing Receiver for Joint Channel Estimation and Decoding in 3D Massive MIMO-OFDM Systems
Sheng Wu, Linling Kuang, Zuyao Ni +4
In this paper, we address the message-passing receiver design for the 3D massive MIMO-OFDM systems. With the aid of the central limit argument and Taylor-series approximation, a co…
Concise Derivation of Complex Bayesian Approximate Message Passing via Expectation Propagation
Xiangming Meng, Sheng Wu, Linling Kuang +1
In this paper, we address the problem of recovering complex-valued signals from a set of complex-valued linear measurements. Approximate message passing (AMP) is one state-of-the-a…
Unequal Error Protected JPEG 2000 Broadcast Scheme with Progressive Fountain Codes
