Robust Precoding Designs for Multiuser MIMO Systems with Limited Feedback
Wentao Zhou, Di Zhang, Merouane Debbah +1
It has been well known that the achievable rate of multiuser multiple-input multiple-output systems with limited feedback is severely degraded by quantization errors when the numbe…
Energy Efficiency Optimization for Multi-cell Massive MIMO: Centralized and Distributed Power Allocation Algorithms
Li You, Yufei Huang, Di Zhang +3
This paper investigates the energy efficiency (EE) optimization in downlink multi-cell massive multiple-input multiple-output (MIMO). In our research, the statistical channel state…
SCMA Codebook Design Based on Uniquely Decomposable Constellation Groups
Xuewan Zhang, Dalong Zhang, Liuqing Yang +3
Sparse code multiple access (SCMA), which helps improve spectrum efficiency (SE) and enhance connectivity, has been proposed as a non-orthogonal multiple access (NOMA) scheme for 5…
Robust Designs of Beamforming and Power Splitting for Distributed Antenna Systems with Wireless Energy Harvesting
Zhengyu Zhu, Sai Huang, Zheng Chu +3
In this paper, we investigate a multiuser distributed antenna system with simultaneous wireless information and power transmission under the assumption of imperfect channel state i…
