Joint Power Allocation and Caching Optimization in Fiber-Wireless Access Networks
Zhuojia Gu, Hancheng Lu, Daren Zhu +1
Fiber-Wireless (FiWi) access networks have been widely deployed due to the complementary advantages of high-capacity fiber backhaul and ubiquitous wireless front end. To meet the i…
Receiver-driven Video Multicast over NOMA Systems in Heterogeneous Environments
Xiaoda Jiang, Hancheng Lu, Chang Wen Chen +1
Non-orthogonal multiple access (NOMA) has shown potential for scalable multicast of video data. However, one key drawback for NOMA-based video multicast is the limited number of la…
Interference-aware User Grouping Strategy in NOMA Systems with QoS Constraints
Fengqian Guo, Hancheng Lu, Daren Zhu +1
To meet the performance and complexity requirements from practical deployment of non-orthogonal multiple access (NOMA) systems, several users are grouped together for NOMA transmis…
Joint Rate and Resource Allocation in Hybrid Digital-Analog Transmission over Fading Channels
Xiaoda Jiang, Hancheng Lu
In hybrid digital-analog (HDA) systems, resource allocation has been utilized to achieve desired distortion performance. However, existing studies on this issue assume error-free d…
Energy and Delay Optimization for Cache-Enabled Dense Small Cell Networks
Hao Wu, Hancheng Lu
Caching popular files in small base stations (SBSs) has been proved to be an effective way to reduce bandwidth pressure on the backhaul links of dense small cell networks (DSCNs).…
Enabling Quality-Driven Scalable Video Transmission over Multi-User NOMA System
Xiaoda Jiang, Hancheng Lu, Chang Wen Chen
Recently, non-orthogonal multiple access (NOMA) has been proposed to achieve higher spectral efficiency over conventional orthogonal multiple access. Although it has the potential…
