Inter-Plane Inter-Satellite Connectivity in LEO Constellations: Beam Switching vs. Beam Steering
Israel Leyva-Mayorga, Maik Röper, Bho Matthiesen +3
Low Earth orbit (LEO) satellite constellations rely on inter-satellite links (ISLs) to provide global connectivity. However, one significant challenge is to establish and maintain…
Hierarchical Resource Allocation: Balancing Throughput and Energy Efficiency in Wireless Systems
Bho Matthiesen, Eduard A. Jorswieck, Petar Popovski
A main challenge of 5G and beyond wireless systems is to efficiently utilize the available spectrum and simultaneously reduce the energy consumption. From the radio resource alloca…
Globally Optimal Beamforming for Rate Splitting Multiple Access
Bho Matthiesen, Yijie Mao, Petar Popovski +1
We consider globally optimal precoder design for rate splitting multiple access in Gaussian multiple-input single-output downlink channels with respect to weighted sum rate and ene…
Intelligent Reflecting Surface Operation under Predictable Receiver Mobility: A Continuous Time Propagation Model
Bho Matthiesen, Emil Björnson, Elisabeth De Carvalho +1
The operation of an intelligent reflecting surface (IRS) under predictable receiver mobility is investigated. We develop a continuous time system model for multipath channels and d…
LEO Small-Satellite Constellations for 5G and Beyond-5G Communications
Israel Leyva-Mayorga, Beatriz Soret, Maik Röper +4
The next frontier towards truly ubiquitous connectivity is the use of Low Earth Orbit (LEO) small-satellite constellations to support 5G and Beyond-5G (B5G) networks. Besides enhan…
Mixed Monotonic Programming for Fast Global Optimization
Bho Matthiesen, Christoph Hellings, Eduard A. Jorswieck +1
While globally optimal solutions to many convex programs can be computed efficiently in polynomial time, this is, in general, not possible for nonconvex optimization problems. Ther…
