An Over-the-Air Multi-User Convolutional Code for URLLC

open access: yesIEEE Open Journal of the Communications Society
URLLC applications impose stringent latency and reliability requirements, making its compliance challenging due to the inherent trade-off between them. These applications typically involve the exchange of small information blocks. Convolutional codes (CC)

Online Spatiotemporally Constrained Reconstruction for Real‐Time Interactive MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 3, Page 1644-1652, March 2026.
ABSTRACT Purpose To develop a low‐latency dynamic MRI reconstruction that provides better spatial and temporal fidelity than contemporary online reconstruction, for localization. Methods We utilize online spatiotemporally constrained reconstruction (STCR) using a computationally efficient augmented Lagrangian solution and a limited number of iterations
