Joint Resource Management for MC-NOMA: A Deep Reinforcement Learning Approach
Shaoyang Wang, Tiejun Lv, Wei Ni +2
This paper presents a novel and effective deep reinforcement learning (DRL)-based approach to addressing joint resource management (JRM) in a practical multi-carrier non-orthogonal…
Analysis and Optimization of Service Delay for Multi-quality Videos in Multi-tier Heterogeneous Network with Random Caching
Xuewei Zhang, Tiejun Lv, Yuan Ren +2
Aiming to minimize service delay, we propose a new random caching scheme in device-to-device (D2D)-assisted heterogeneous network. To support diversified viewing qualities of multi…
Economical Caching for Scalable Videos in Cache-enabled Heterogeneous Networks
Xuewei Zhang, Tiejun Lv, Yuan Ren +3
We develop the optimal economical caching schemes in cache-enabled heterogeneous networks, while delivering multimedia video services with personalized viewing qualities to mobile…
Energy-Efficient Caching for Scalable Videos in Heterogeneous Networks
Xuewei Zhang, Tiejun Lv, Wei Ni +3
By suppressing repeated content deliveries, wireless caching has the potential to substantially improve the energy efficiency (EE) of the fifth generation (5G) communication networ…
An Improved and More Accurate Expression for a PDF Related to Eigenvalue-Based Spectrum Sensing
Fuhui Zhou, Norman C. Beaulieu
Cooperative spectrum sensing based on the limiting eigenvalue ratio of the covariance matrix offers superior detection performance and overcomes the noise uncertainty problem. Whil…
Equivalent Codes, Optimality, and Performance Analysis of OSTBC: Textbook Study
Alex E. Geyer, Reza Nikjah, Sergiy A. Vorobyov +1
An equivalent model for a multi-input multi-output (MIMO) communication system with orthogonal space-time block codes (OSTBCs) is proposed based on a newly revealed connection betw…
