Error Floor of ML-Decoded Spinal Codes in the Finite Blocklength Regime
Aimin Li, Shaohua Wu, Xiaomeng Chen +1
Spinal codes is a new family of capacity-achieving rateless codes that has been shown to achieve better rate performance compared to Raptor codes, Strider codes, and rateless Low-D…
Towards Goal-Oriented Semantic Communications: New Metrics, Framework, and Open Challenges
Aimin Li, Shaohua Wu, Siqi Meng +3
Since Shannon's pioneering masterpiece which established the prototype of modern information theory, the goal of communications has long been promising accurate message reconstruct…
Joint Transmission and Control in a Goal-oriented NOMA Network
Kunpeng Liu, Shaohua Wu, Aimin Li +1
Goal-oriented communication shifts the focus from merely delivering timely information to maximizing decision-making effectiveness by prioritizing the transmission of high-value in…
Sampling to Achieve the Goal: An Age-aware Remote Markov Decision Process
Aimin Li, Shaohua Wu, Gary C. F. Lee +2
Age of Information (AoI) has been recognized as an important metric to measure the freshness of information. Central to this consensus is that minimizing AoI can enhance the freshn…
Optimal Sampling for Uncertainty-of-Information Minimization in a Remote Monitoring System
Xiaomeng Chen, Aimin Li, Shaohua Wu
In this paper, we study a remote monitoring system where a receiver observes a remote binary Markov source and decides whether to sample and transmit the state through a randomly d…
