Receiver-Centric Generative Semantic Communications
Xunze Liu, Yifei Sun, Zhaorui Wang +4
This paper investigates semantic communications between a transmitter and a receiver, where original data, such as videos of interest to the receiver, is stored at the transmitter.…
Reconfigurable Intelligent Surface Assisted Semantic Communication Systems
Jiajia Shi, Tse-Tin Chan, Haoyuan Pan +1
Semantic communication, which focuses on conveying the meaning of information rather than exact bit reconstruction, has gained considerable attention in recent years. Meanwhile, re…
Channel Cycle Time: A New Measure of Short-term Fairness
Pengfei Shen, Yulin Shao, Haoyuan Pan +2
This paper puts forth a new metric, dubbed channel cycle time (CCT), to measure the short-term fairness of communication networks. CCT characterizes the average duration between tw…
Device Activity Detection in mMTC with Low-Resolution ADC: A New Protocol
Zhaorui Wang, Ya-Feng Liu, Ziyue Wang +3
This paper investigates the effect of low-resolution analog-to-digital converters (ADCs) on device activity detection in massive machine-type communications (mMTC). The low-resolut…
Minimizing Age of Collection for Multiple Access in Wireless Industrial Internet of Things
Jiaxin Liang, Tse-Tin Chan, Haoyuan Pan
This paper investigates the information freshness of Industrial Internet of Things (IIoT) systems, where each IoT device makes a partial observation of a common target and transmit…
Timely Status Update in Relay-Assisted Cooperative Communications
Haoyuan Pan, Jian Feng, Tse-Tin Chan +2
We investigate the age of information (AoI) of a relay-assisted cooperative communication system, where a source node sends status update packets to the destination node as timely…
Age of Information in Physical-Layer Network Coding Enabled Two-Way Relay Networks
Haoyuan Pan, Tse-Tin Chan, Victor C. M. Leung +1
This paper investigates the information freshness of two-way relay networks (TWRN) operated with physical-layer network coding (PNC). Information freshness is quantified by age of…
Information Update: TDMA or FDMA?
Haoyuan Pan, Soung Chang Liew
This paper studies information freshness in information update systems operated with TDMA and FDMA. Information freshness is characterized by a recently introduced metric, age of i…
Practical Power-Balanced Non-Orthogonal Multiple Access
Haoyuan Pan, Lu Lu, Soung Chang Liew
This paper investigates practical 5G strategies for power-balanced non-orthogonal multiple access (NOMA). By allowing multiple users to share the same time and frequency, NOMA can…
Multiuser Rate-Diverse Network-Coded Multiple Access
Haoyuan Pan, Lu Lu, Soung Chang Liew
This paper presents the first Network-Coded Multiple Access (NCMA) system with multiple users adopting different signal modulations, referred to as rate-diverse NCMA. A distinguish…
Network-Coded Multiple Access with High-order Modulations
Haoyuan Pan, Lu Lu, Soung Chang Liew
This paper presents the first network-coded multiple access (NCMA) system prototype operated on high-order modulations up to 16-QAM. NCMA jointly exploits physical-layer network co…
