Solving Linear Inverse Problems using Higher-Order Annealed Langevin Diffusion
Nicolas Zilberstein, Ashutosh Sabharwal, Santiago Segarra
We propose a solution for linear inverse problems based on higher-order Langevin diffusion. More precisely, we propose pre-conditioned second-order and third-order Langevin dynamic…
Full-Duplex Wireless for 6G: Progress Brings New Opportunities and Challenges
Besma Smida, Ashutosh Sabharwal, Gabor Fodor +3
The use of in-band full-duplex (FD) enables nodes to simultaneously transmit and receive on the same frequency band, which challenges the traditional assumption in wireless network…
A Deep Reinforcement Learning-Based Resource Scheduler for Massive MIMO Networks
Qing An, Santiago Segarra, Chris Dick +2
The large number of antennas in massive MIMO systems allows the base station to communicate with multiple users at the same time and frequency resource with multi-user beamforming.…
Accelerated massive MIMO detector based on annealed underdamped Langevin dynamics
Nicolas Zilberstein, Chris Dick, Rahman Doost-Mohammady +2
We propose a multiple-input multiple-output (MIMO) detector based on an annealed version of the \emph{underdamped} Langevin (stochastic) dynamic. Our detector achieves state-of-the…
Consensus ADMM-Based Distributed Simultaneous Imaging & Communication
Nishant Mehrotra, Ashutosh Sabharwal, César A. Uribe
This paper takes the first steps toward enabling wireless networks to perform both imaging and communication in a distributed manner. We propose Distributed Simultaneous Imaging an…
Distributed Generalized Wirtinger Flow for Interferometric Imaging on Networks
Sean M. Farrell, Ashok Veeraraghavan, Ashutosh Sabharwal +1
We study the problem of decentralized interferometric imaging over networks, where agents have access to a subset of local radar measurements and can compute pair-wise correlations…
