PASA: A Priori Adaptive Splitting Algorithm for the Split Delivery Vehicle Routing Problem
Nariman Torkzaban, Anousheh Gholami, John S. Baras +1
The split delivery vehicle routing problem (SDVRP) is a relaxed variant of the capacitated vehicle routing problem (CVRP) where the restriction that each customer is visited precis…
Enabling Cooperative Hybrid Beamforming in TDD-based Distributed MIMO Systems
Nariman Torkzaban, Amir Khojastepour, John S. Baras
Distributed massive MIMO networks are envisioned to realize cooperative multi-point transmission in next-generation wireless systems. For efficient cooperative hybrid beamforming,…
Blind Cyclic Prefix-based CFO Estimation in MIMO-OFDM Systems
Nariman Torkzaban, Amir Khojastepour, John S. Baras
Low-complexity estimation and correction of carrier frequency offset (CFO) are essential in orthogonal frequency division multiplexing (OFDM). In this paper, we propose a low-overh…
Mobile Network Slicing under Demand Uncertainty: A Stochastic Programming Approach
Anousheh Gholami, Nariman Torkzaban, John S. Baras
Network slicing enables the deployment of multiple dedicated virtual sub-networks, i.e. slices on a shared physical infrastructure. Unlike traditional one-size-fits-all resource pr…
Capacitated Beam Placement for Multi-beam Non-Geostationary Satellite Systems
Nariman Torkzaban, Asim Zoulkarni, Anousheh Gholami +1
Non-geostationary (NGSO) satellite communications systems have attracted a lot of attention both from industry and academia, over the past several years. Beam placement is among th…
