Bisparse Blind Deconvolution through Hierarchical Sparse Recovery
Axel Flinth, Ingo Roth, Gerhard Wunder
The hierarchical sparsity framework, and in particular the HiHTP algorithm, has been successfully applied to many relevant communication engineering problems recently, particularly…
Power of Explanations: Towards automatic debiasing in hate speech detection
Yi Cai, Arthur Zimek, Gerhard Wunder +1
Hate speech detection is a common downstream application of natural language processing (NLP) in the real world. In spite of the increasing accuracy, current data-driven approaches…
One-Shot Messaging at Any Load Through Random Sub-Channeling in OFDM
Gerhard Wunder, Axel Flinth, Benedikt Groß
Compressive Sensing has well boosted massive random access protocols over the last decade. In this paper we apply an orthogonal FFT basis as it is used in OFDM, but subdivide its i…
Age-of-Information in Clocked Networks
R. Schoeffauer, G. Wunder
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 agen…
An Algorithm for Exact Numerical Age-of-Information Evaluation in Multi-Agent Systems
Richard Schoeffauer, Gerhard Wunder
We present an algorithm for the numerical evaluation of the state-space distribution of an Age-of-Information network. Given enough computational resources, the evaluation can be p…
Open or not open: Are conventional radio access networks more secure and trustworthy than Open-RAN?
Felix Klement, Stefan Katzenbeisser, Vincent Ulitzsch +5
The Open RAN architecture is a promising and future-oriented architecture. It is intended to open up the radio access network (RAN) and enable more innovation and competition in th…
