Does the Cross-Talk Between Nonlinear Modes Limit the Performance of NFDM Systems?
Vahid Aref, Son T. Le, Henning Buelow
We show a non-negligible cross-talk between nonlinear modes in Nonlinear Frequency-Division Multiplexed system when data is modulated over the nonlinear Fourier spectrum, both the…
Quantized Precoding for Multi-Antenna Downlink Channels with MAGIQ
Andrei Nedelcu, Fabian Steiner, Markus Staudacher +5
A multi-antenna, greedy, iterative, and quantized (MAGIQ) precoding algorithm is proposed for downlink channels. MAGIQ allows a straightforward integration with orthogonal frequenc…
Achieving CMMI Level 2 with Enhanced Extreme Programming Approach
Tuomo Kähkönen, Pekka Abrahamsson
The relationship between agile methods and Software Engineering Institute's CMM approach is often debated. Some authors argue that the approaches are compatible, while others have…
Deep convolutional neural networks for estimating porous material parameters with ultrasound tomography
Timo Lähivaara, Leo Kärkkäinen, Janne M. J. Huttunen +1
We study the feasibility of data based machine learning applied to ultrasound tomography to estimate water-saturated porous material parameters. In this work, the data to train the…
Methods for compressible fluid simulation on GPUs using high-order finite differences
Johannes Pekkilä, Miikka S. Väisälä, Maarit J. Käpylä +2
We focus on implementing and optimizing a sixth-order finite-difference solver for simulating compressible fluids on a GPU using third-order Runge-Kutta integration. Since graphics…
Green Base Station Placement for Microwave Backhaul Links
Alonso Silva, Antonia Masucci
Wireless mobile backhaul networks have been proposed as a substitute in cases in which wired alternatives are not available due to economical or geographical reasons. In this work,…
