Polarized Low-Density Parity-Check Codes on the BSC
Binbin Gao, Huarui Yin, Zhengdao Wang
The connections between variable nodes and check nodes have a great influence on the performance of low-density parity-check (LDPC) codes. Inspired by the unique structure of polar…
Optimization of a Two-Hop Network with Energy Conferencing Relays
Sharief Abdel-Razeq, Ming Zhao, Shengli Zhou +1
This paper considers a two-hop network consisting of a source, two parallel half-duplex relay nodes, and two destinations. While the destinations have an adequate power supply, the…
On the Sublinear Convergence of Randomly Perturbed Alternating Gradient Descent to Second Order Stationary Solutions
Songtao Lu, Mingyi Hong, Zhengdao Wang
The alternating gradient descent (AGD) is a simple but popular algorithm which has been applied to problems in optimization, machine learning, data ming, and signal processing, etc…
A Nonconvex Splitting Method for Symmetric Nonnegative Matrix Factorization: Convergence Analysis and Optimality
Songtao Lu, Mingyi Hong, Zhengdao Wang
Symmetric nonnegative matrix factorization (SymNMF) has important applications in data analytics problems such as document clustering, community detection and image segmentation. I…
Many Access for Small Packets Based on Precoding and Sparsity-aware Recovery
Ronggui Xie, Huarui Yin, Xiaohui Chen +1
Modern mobile terminals produce massive small data packets. For these short-length packets, it is inefficient to follow the current multiple access schemes to allocate transmission…
Achievable Rates and Training Optimization for Uplink Multiuser Massive MIMO Systems
Songtao Lu, Zhengdao Wang
We study the performance of uplink transmission in a large-scale (massive) MIMO system, where all the transmitters have single antennas and the base station has a large number of a…
