[2016] Reflection and transmission of ultra-wideband pulses for detection of vascular pressure variation and spatial resolution within soft tissues (Martin Mackenberg, Klaas Rackebrandt, Christian Bollmeyer, Philipp Wegerich, Hartmut Gehring, Horst Hellbrück), In Biomedical Physics & Engineering Express, volume 2, 2016. [bib] [pdf] [abstract]
Ultra-wideband signals have a variety of applications. An upcoming medical application is the detection of the heart rate of patients. However, current UWB systems provide poor resolution and are only able to detect vessels with a large diameter, e.g. the aorta. The detection and quantification of vascular dilation of thinner vessels is essential to develop wearable ultra-wideband based devices for real-time detection of cardiovascular conditions of the extremities. The reflection and transmission processes of those signals within inhomogeneous bodies are complex and their prediction is challenging. In this paper, we present an experimental setup (UWB system; phantom) for the detection of vascular dilation within soft tissues. Furthermore, we suggest a theoretical simulation model for the prediction of the reflection of ultra-wideband pulses and compare these simulated predictions to results of measurements within the phantom. The results verify that we are able to identify vascular dilation within the simulation model and the experimental setup, depending on the depth of the vessel (20 mm, 40 mm, 60 mm).

[2017] Optical Underwater Distance Estimation (Mathias Pelka, Martin Mackenberg, Christan Funda, Horst Hellbrück), In Oceans MTS/IEEE, 2017. [bib] [abstract]
Data communication with high data rate and precise underwater positioning with an accuracy of several centimeters is a problem. Precise positioning is important for autonomous operation and helps conserve energy which is important for many tasks. State-of-the-art acoustic communication faces difficulties underwater, e.g. multipath fading or variation of propagation speed. In this work, we propose optical distance estimation, which is the foundation for positioning. We combine the Beer-Lambert law and the inverse-square-law to model the channel of the medium. We investigate different wavelengths and employ curve fitting based on the Levenberg-Marquardt algorithm to determine the unknown coefficients of the model e.g. absorption. Our evaluation shows promising results and distance estimation of up to 25~m is possible. In stream water we determined the mean error for the optical distance estimation of 0.04m.
[2016] A Flexible and Modular Platform for Development of Short-Range Underwater Communication (Gunther Ardelt, Martin Mackenberg, Jan Markmann, Tim Esemann, Horst Hellbrück), In The Eleventh International Conference on Underwater Networks and Systems, 2016. [bib] [abstract]
The development process of short-range underwater communication systems consists of di erent phases. Each phase comprises a multitude of speci c requirements to the development platform. Typically, the utilized hardware and software is custom-built for each phase and wireless technology. Thus, the available platforms are usually not exible and only usable for a single development phase or a single wireless technology. Furthermore, the modi cation and adaption between the phases and technologies are costly and time-consuming. Platforms providing the exibility to switch between phases or even wireless technologies are either expensive or are not suitable to be integrated into underwater equipment. We developed a exible and modular platform consisting of a controller and di erent front ends. The platform is capable of performing complex tasks during all development phases. To achieve high performance with more complex modulation schemes, we combine an embedded Linux processor with a eld programmable gate array (FPGA) for computational demanding tasks. We show that our platform is capable of supporting the development of short-range underwater communication systems using a variety of wireless underwater communication technologies.
[2015] Simulation and Evaluation of an Optical Channel Model for Underwater Communication (Martin Mackenberg, Tim Esemann, Horst Hellbrück), In Proceedings of the International Conference on UnderWater Networks and Systems 2015, 2015. [bib] [abstract]
Underwater communication gains increasing importance with rising need for autonomous underwater vehicles (AUV) and underwater infrastructure. Many applications require only a short range link up to a few meters, but high data rates up to several megabit per second. Optical communication is a promising solution for these applications. However, the performance of underwater optical communication is highly dependent on water conditions. Previous implementations rarely provide theoretical background on design decisions and rely on experimental results to verify range and data rates. We propose a model that enables an evaluation of range and signal strength dependent on the most important components of seawater. Furthermore, we implement a prototype based on simulation results and validate the model with measurement data.
Workshop Beiträge
[2014] Software Defined Transceiver for Underwater Communication (Martin Mackenberg, Christian Janicke, Tim Esemann, Horst Hellbrück), In Proceedings of the European Workshop on Testbed based Wireless Research, 2014. [bib] [abstract]
New applications for autonomous underwater vehicles require underwater wireless communication with data rates up to several megabit per second and a transmission range up to several meter. Regular radio transceivers achieve a poor performance in seawater. Therefore, our project evaluates and implements new approaches for optical, acoustic and electric underwater communication. The goal is to implement a flexible software defined transceiver consisting of a FPGA with exchangeable communication modules.
