Talking Ink: A Flow-Based Multi-Molecule Molecular Communication Testbed for Effective Channel Modeling and Detector Benchmarking
Alexander Wietfeld, Krupakar Duvva, Jiachen Xiao +1
Practical molecular communication (MC) testbeds are essential for translating theoretical concepts toward future applications while retaining physical realism, accessibility, and e…
DBMC-aNOMAly: Asynchronous NOMA with Pilot-Symbol Optimization Protocol for Diffusion-Based Molecular Communication Networks
Alexander Wietfeld, Wolfgang Kellerer
Multiple access (MA) schemes can enable cooperation between multiple nodes in future diffusion-based molecular communication (DBMC) networks. Non-orthogonal MA for DBMC networks (D…
A Causal Diffusion Model for Video Reconstruction from Ultra-Low-Bitrate Representations
Cem Eteke, Batuhan Tosun, Martin Piccolrovazzi +3
We study video reconstruction from ultra-low-bitrate representations, where the primary challenge shifts from encoding to decoding. In this regime, reconstruction with classical an…
BIR-Adapter: A parameter-efficient diffusion adapter for blind image restoration
Cem Eteke, Alexander Griessel, Wolfgang Kellerer +1
We introduce the BIR-Adapter, a parameter-efficient diffusion adapter for blind image restoration. Diffusion-based restoration methods have demonstrated promising performance in ad…
ChemSICal-Net: Timing-Controlled Chemical Reaction Network for Successive Interference Cancellation in Molecular Multiple Access
Alexander Wietfeld, Oguz Turgut, Eneritz Somoza RodrÃguez +1
MC networks are envisioned to enable synthetic information exchange between nanoscale biological entities. For many algorithm proposals in the MC research field, the question of im…
A Hands-On Molecular Communication Testbed for Undergraduate Education
Arne Gaedeken, Alexander Wietfeld, Yaning Zhao +3
This work presents a hands-on molecular communication (MC) testbed developed for the undergraduate Communication Engineering lab course at the Institute for Communications Technolo…
