RISnet: A Scalable Approach for Reconfigurable Intelligent Surface Optimization with Partial CSI

1 code implementation • 1 May 2023 • Bile Peng, Karl-Ludwig Besser, Ramprasad Raghunath, Vahid Jamali, Eduard A. Jorswieck

Two major challenges of this problem are the high dimensionality due to the large number of RIS elements and the difficulty to obtain the full channel state information (CSI), which is assumed known in many algorithms proposed in the literature.

Approaching Globally Optimal Energy Efficiency in Interference Networks via Machine Learning

1 code implementation • 25 Nov 2022 • Bile Peng, Karl-Ludwig Besser, Ramprasad Raghunath, Eduard A. Jorswieck

This optimization problem is non-convex and its global optimum is difficult to find.

On Fading Channel Dependency Structures with a Positive Zero-Outage Capacity

2 code implementations • 4 Feb 2021 • Karl-Ludwig Besser, Pin-Hsun Lin, Eduard A. Jorswieck

Based on a systematic copula approach, we show that there exists a set of dependency structures for which positive ZOCs can be achieved for both maximum ratio combining (MRC) and selection combining (SC).
