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…
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…
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
Zhao Chen, Mai Xu, Luiguo Yin +1
This paper proposes a novel scheme, based on progressive fountain codes, for broadcasting JPEG 2000 multimedia. In such a broadcast scheme, progressive resolution levels of images/…
Rateless Codes with Progressive Recovery for Layered Multimedia Delivery
Zhao Chen, Liuguo Yin, Mai Xu +1
This paper proposes a novel approach, based on unequal error protection, to enhance rateless codes with progressive recovery for layered multimedia delivery. With a parallel encodi…
On the Linear Precoder Design for MIMO Channels with Finite-Alphabet Inputs and Statistical CSI
Weiliang Zeng, Chengshan Xiao, Mingxi Wang +1
This paper investigates the linear precoder design that maximizes the average mutual information of multiple-input multiple-output channels with finite-alphabet inputs and statisti…
Linear Precoding for Relay Networks with Finite-Alphabet Constraints
Weiliang Zeng, Chengshan Xiao, Mingxi Wang +1
In this paper, we investigate the optimal precoding scheme for relay networks with finite-alphabet constraints. We show that the previous work utilizing various design criteria to…
