A Unifying View of OTFS and Its Many Variants
Qinwen Deng, Yao Ge, Zhi Ding
High mobility environment leads to severe Doppler effects and poses serious challenges to the conventional physical layer based on the widely popular orthogonal frequency division…
OTFS Signaling for SCMA With Coordinated Multi-Point Vehicle Communications
Yao Ge, Qinwen Deng, David González G. +2
This paper investigates an uplink coordinated multi-point (CoMP) coverage scenario, in which multiple mobile users are grouped for sparse code multiple access (SCMA), and served by…
Image Processing via Multilayer Graph Spectra
Songyang Zhang, Qinwen Deng, Zhi Ding
Graph signal processing (GSP) has become an important tool in image processing because of its ability to reveal underlying data structures. Many real-life multimedia datasets, howe…
Signal Processing over Multilayer Graphs: Theoretical Foundations and Practical Applications
Songyang Zhang, Qinwen Deng, Zhi Ding
Signal processing over single-layer graphs has become a mainstream tool owing to its power in revealing obscure underlying structures within data signals. However, many real-life d…
Point Cloud Resampling Through Hypergraph Signal Processing
Qinwen Deng, Songyang Zhang, Zhi Ding
Three-dimensional (3D) point clouds are important data representations in visualization applications. The rapidly growing utility and popularity of point cloud processing strongly…
