Polar Decoding on Sparse Graphs with Deep Learning
Weihong Xu, Xiaohu You, Chuan Zhang +1
In this paper, we present a sparse neural network decoder (SNND) of polar codes based on belief propagation (BP) and deep learning. At first, the conventional factor graph of polar…
Low Complexity Iterative Detection for a Large-scale Distributed MIMO Prototyping System
Yuan Feng, Menghan Wang, Dongming Wang +1
In this paper, we study the low-complexity iterative soft-input soft-output (SISO) detection algorithm in a large-scale distributed multiple-input multiple-output (MIMO) system. Th…

Wideband mmWave Channel Estimation for Hybrid Massive MIMO with Low-Precision ADCs
Yucheng Wang, Wei Xu, Hua Zhang +1
In this article, we investigate channel estimation for wideband millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) under hybrid architecture with lowprecision a…
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…
AI for 5G: Research Directions and Paradigms
Xiaohu You, Chuan Zhang, Xiaosi Tan +2
The 5th wireless communication (5G) techniques not only fulfil the requirement of times increase of internet traffic in the next decade, but also offer the underlying techn…
