MIMO Channel Information Feedback Using Deep Recurrent Network
Chao Lu, Wei Xu, Hong Shen +2
In a multiple-input multiple-output (MIMO) system, the availability of channel state information (CSI) at the transmitter is essential for performance improvement. Recent convoluti…
Performance Analysis of Multi-Cell Millimeter Wave Massive MIMO Networks with Low-Precision ADCs
Jindan Xu, Wei Xu, Hua Zhang +2
In this paper, we investigate a multi-cell millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) network with low-precision analog-to-digital converters (ADCs) at…
Improving Wireless Physical Layer Security via D2D Communication
Hao Xu, Cunhua Pan, Wei Xu +3
This paper investigates the physical layer security issue of a device-to-device (D2D) underlaid cellular system with a multi-antenna base station (BS) and a multi-antenna eavesdrop…
A Framework on Hybrid MIMO Transceiver Design based on Matrix-Monotonic Optimization
Chengwen Xing, Xin Zhao, Wei Xu +2
Hybrid transceiver can strike a balance between complexity and performance of multiple-input multiple-output (MIMO) systems. In this paper, we develop a unified framework on hybrid…
An Enhanced SCMA Detector Enabled by Deep Neural Network
Chao Lu, Wei Xu, Hong Shen +2
In this paper, we propose a learning approach for sparse code multiple access (SCMA) signal detection by using a deep neural network via unfolding the procedure of message passing…
Learning Oriented Cross-Entropy Approach to User Association in Load-Balanced HetNet
Xietian Huang, Wei Xu, Guo Xie +2
This letter considers optimizing user association in a heterogeneous network via utility maximization, which is a combinatorial optimization problem due to integer constraints. Dif…
