Channel Estimation with Asynchronous Reception for User-Centric Cell-Free MIMO Systems
Xuyang Sun, Hussein A. Ammar, Raviraj Adve +2
The user-centric, cell-free wireless network is a promising next-generation communication system, but signal synchronization issues arise due to distributed access points and lack…
Percentile Optimization in Wireless Networks- Part I: Power Control for Max-Min-Rate to Sum-Rate Maximization (and Everything in Between)
Ahmad Ali Khan, Raviraj Adve
Improving throughput for cell-edge users through coordinated resource allocation has been a long-standing driver of research in wireless cellular networks. While a variety of wirel…
Percentile Optimization in Wireless Networks- Part II: Beamforming for Cell-Edge Throughput Maximization
Ahmad Ali Khan, Raviraj Adve
Part I of this two-part paper focused on the formulation of percentile problems, complexity analysis, and development of power control algorithms via the quadratic fractional trans…
Handoffs in User-Centric Cell-Free MIMO Networks: A POMDP Framework
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
We study the problem of managing handoffs (HOs) in user-centric cell-free massive MIMO (UC-mMIMO) networks. Motivated by the importance of controlling the number of HOs and by the…
POMDP-based Handoffs for User-Centric Cell-Free MIMO Networks
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
We propose to control handoffs (HOs) in user-centric cell-free massive MIMO networks through a partially observable Markov decision process (POMDP) with the state space representin…
Selectivity of Protein Interactions Stimulated by Terahertz Signals
Hadeel Elayan, Andrew W. Eckford, Raviraj Adve
It has been established that Terahertz (THz) band signals can interact with biomolecules through resonant modes. Specifically, of interest here, protein activation. Our research go…
