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…
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…
Utility-Energy Efficiency Oriented User Association with Power Control in Heterogeneous Networks
Xietian Huang, Wei Xu, Hong Shen +2
This letter investigates optimizing utility-energy efficiency (UEE), defined as the achieved network utility when consuming a unit of power, rather than a typical energy efficiency…
Hybrid Precoding Architecture for Massive Multiuser MIMO with Dissipation: Sub-Connected or Fully-Connected Structures?
Jingbo Du, Wei Xu, Hong Shen +2
In this paper, we study the hybrid precoding structures over limited feedback channels for massive multiuser multiple-input multiple-output (MIMO) systems. We focus on the system p…
