Closed-form Solution of Wahba's Problem for Pairwise Similar Quaternions
Hristina Radak, Christian Scheunert, Frank H. P. Fitzek
Wahba's problem is fundamental to spacecraft attitude estimation, seeking the optimal rotation that minimizes the weighted misalignment between sets of vector observations. Traditi…
On solutions of singular Sylvester equations in quaternions
Hristina Radak, Christian Scheunert, Frank H. P. Fitzek
We study the singular Sylvester equations and over the quaternions. Working entirely within quaternion algebra, we give constructive derivations of the…
An Overview of the NET Playground -- A Heterogeneous, Multi-Functional Network Test Bed
Paul Schwenteck, Sandra Zimmermann, Caspar von Lengerke +3
This paper provides an overview of the hardware and software components used in our test bed project the NET Playground. All source information is stored in the GitLab repository (…
Weak Secrecy in the Multi-Way Untrusted Relay Channel with Compute-and-Forward
Johannes Richter, Christian Scheunert, Sabrina Engelmann +1
We investigate the problem of secure communications in a Gaussian multi-way relay channel applying the compute-and-forward scheme using nested lattice codes. All nodes employ half-…
