On the Design of Multi-Dimensional Irregular Repeat-Accumulate Lattice Codes
Min Qiu, Lei Yang, Yixuan Xie +1
Most multi-dimensional (more than two dimensions) lattice partitions only form additive quotient groups and lack multiplication operations. This prevents us from constructing latti…
User-centric C-RAN Architecture for Ultra-dense 5G Networks: Challenges and Methodologies
Cunhua Pan, Maged Elkashlan, Jiangzhou Wang +2
Ultra-dense networks (UDN) constitute one of the most promising techniques of supporting the 5G mobile system. By deploying more small cells in a fixed area, the average distance b…
Information-Coupled Turbo Codes for LTE Systems
Lei Yang, Yixuan Xie, Xiaowei Wu +3
We propose a new class of information-coupled (IC) Turbo codes to improve the transport block (TB) error rate performance for long-term evolution (LTE) systems, while keeping the h…
A Survey on Non-Orthogonal Multiple Access for 5G Networks: Research Challenges and Future Trends
Zhiguo Ding, Xianfu Lei, George K. Karagiannidis +3
Non-orthogonal multiple access (NOMA) is an essential enabling technology for the fifth generation (5G) wireless networks to meet the heterogeneous demands on low latency, high rel…
Optimal Resource Allocation for Power-Efficient MC-NOMA with Imperfect Channel State Information
Zhiqiang Wei, Derrick Wing Kwan Ng, Jinhong Yuan +1
In this paper, we study power-efficient resource allocation for multicarrier non-orthogonal multiple access (MC-NOMA) systems. The resource allocation algorithm design is formulate…
Wireless Powered Dense Cellular Networks: How Many Small Cells Do We Need?
Lifeng Wang, Kai-Kit Wong, Robert W. Heath +1
This paper focuses on wireless powered 5G dense cellular networks, where base station (BS) delivers energy to user equipment (UE) via the microwave radiation in sub-6 GHz or millim…
