Compressed Control of Complex Wireless Networks
Beatriz Lorenzo, Savo Glisic
Future wireless networks are envisioned to integrate multi-hop, multi-operator, multi-technology (m3) components in order to meet the increasing traffic demand at an acceptable pri…
Fast Orthonormal Sparsifying Transforms Based on Householder Reflectors
Cristian Rusu, Nuria Gonzalez-Prelcic, Robert Heath
Dictionary learning is the task of determining a data-dependent transform that yields a sparse representation of some observed data. The dictionary learning problem is non-convex,…
Channel Estimation for Hybrid Architecture Based Wideband Millimeter Wave Systems
Kiran Venugopal, Ahmed Alkhateeb, Nuria González Prelcic +1
Hybrid analog and digital precoding allows millimeter wave (mmWave) systems to achieve both array and multiplexing gain. The design of the hybrid precoders and combiners, though, i…
Architecting Time-Critical Big-Data Systems
Pablo Basanta-Val, Neil Audsley, Andy Wellings +2
- Current infrastructures for developing big-data applications are able to process --via big-data analytics-huge amounts of data, using clusters of machines that collaborate to per…
Joint Resource Bidding and Tipping Strategies in Multi-hop Cognitive Networks
Beatriz Lorenzo, Ivana Kovacevic, Ana Peleteiro +2
In multi-hop secondary networks, bidding strategies for spectrum auction, route selection and relaying incentives should be jointly considered to establish multi-hop communication.…
Delayed collapses of BECs in relation to AdS gravity
Anxo F. Biasi, Javier Mas, Angel Paredes
We numerically investigate spherically symmetric collapses in the Gross-Pitaevskii equation with attractive nonlinearity in a harmonic potential. Even below threshold for direct co…
