FAST: Fidelity-Adjustable Semantic Transmission over Heterogeneous Wireless Networks
Peichun Li, Guoliang Cheng, Jiawen Kang +4
In this work, we investigate the challenging problem of on-demand semantic communication over heterogeneous wireless networks. We propose a fidelity-adjustable semantic transmissio…
Energy-Efficient Delay-Constrained Transmission and Sensing for Cognitive Radio Systems
Yuan Wu, Vincent K. N. Lau, Danny H. K. Tsang +1
In this work we study energy-efficient transmission for Cognitive Radio (CR) which opportunistically operates on Primary User's (PU's) channel through spectrum sensing. Spectrum se…
Globally Optimal Distributed Power Control for Nonconcave Utility Maximization
Li Ping Qian, Ying Jun, Zhang +1
Transmit power control in wireless networks has long been recognized as an effective mechanism to mitigate co-channel interference. Due to the highly non-convex nature, optimal pow…
MAPEL: Achieving Global Optimality for a Non-convex Wireless Power Control Problem
Liping Qian, Ying Jun Zhang, Jianwei Huang
Achieving weighted throughput maximization (WTM) through power control has been a long standing open problem in interference-limited wireless networks. The complicated coupling bet…
