A Coordinate Descent Approach to Atomic Norm Denoising
Ruifu Li, Danijela Cabric
Atomic norm minimization is of great interest in various applications of sparse signal processing including super-resolution line-spectral estimation and signal denoising. In pract…
Machine Learning Prediction for Phase-less Millimeter-Wave Beam Tracking
Benjamin W. Domae, Veljko Boljanovic, Ruifu Li +1
Future wireless networks may operate at millimeter-wave (mmW) and sub-terahertz (sub-THz) frequencies to enable high data rate requirements. While large antenna arrays are critical…
Machine Learning Assisted Phase-less Millimeter-Wave Beam Alignment in Multipath Channels
Benjamin W. Domae, Ruifu Li, Danijela Cabric
Communication systems at millimeter-wave (mmW) and sub-terahertz frequencies are of increasing interest for future high-data rate networks. One critical challenge faced by phased a…
Rainbow-link: Beam-Alignment-Free and Grant-Free mmW Multiple Access using True-Time-Delay Array
Ruifu Li, Han Yan, Danijela Cabric
The millimeter-wave (mmW) communications is a key enabling technology in 5G to provide ultra-high throughput. Current mmW technologies rely on analog phased arrays to realize beamf…
