Autor: Schoeffauer, R., Wunder, G.

We derive key features of the Age-of-Information distribution in a system whose activities are strictly limited to periodic instances on a global time grid. In particular, one agent periodically generates updates while the other agent periodically us

Hierarchical restricted isometry property for Kronecker product measurements

Autor: Roth, I., Flinth, A., Kueng, R., Eisert, J., Wunder, G.

Hierarchically sparse signals and Kronecker product structured measurements arise naturally in a variety of applications. The simplest example of a hierarchical sparsity structure is two-level $(s,\sigma)$-hierarchical sparsity which features $s$-blo

On Interference Alignment and the Deterministic Capacity for Cellular Channels with Weak Symmetric Cross Links

Autor: Buehler, J., Wunder, G.

In this paper, we study the uplink of a cellular system using the linear deterministic approximation model, where there are two users transmitting to a receiver, mutually interfering with a third transmitter communicating with a second receiver. We g

On Capacity Computation for the Two-User Binary Multiple-Access Channel

Autor: Bühler, J., Wunder, G.

This paper deals with the problem of computing the boundary of the capacity region for the memoryless two-user binary-input binary-output multiple-access channel ((2,2;2)-MAC), or equivalently, the computation of input probability distributions maxim
