We offer bachelor, master and student theses in various subject areas. If you are interested in writing a thesis in the following areas, please contact the respective supervisors! It is possible to adapt the topics in their scope depending on the type of work.
- Digital signal processing conception, simulation and implementation of a MIMO transceiver for wireless in vitro communication
Supervisor: Horst Hellbrück
Subject Area
Wireless communication in vitro based on an electric near field should be non-directional in some medical applications, e.g. using a MIMO antenna. Digital signal processing should be conceptualized, simulated and implemented.
Tasks
- Familiarization with existing hardware
- Conception, simulation, implementation
- Documentation
Requirements
- Digital Signal Processing
- Embedded systems, VHDL/Verilog/C programming, MATLAB
- Curiosity, independent work
- Comparison of filter systems in a CIR-based 2-dimensional location cell.
Supervisor: Horst Hellbrück, Sven Ole Schmidt
Subject Area
In Industrie 4.0 applications, the product must be located many times. Since manual scans, such as barcodes, are inconvenient and can lead to massive errors, non-manual locating is used in industrial halls. In many wireless location systems, transmission time is used to determine the distance between the transmitting anchor and the receiving tag. Therefore, the use of channel impulse response (CIR) instead of multiple anchors is a major issue in current locating research topics. Here, the analysis of the transmission environment, including errors and distortions, is important because the accurate localization of the tag depends on good models.
Details
The goal is to simulate a 2-dimensional rectangular space. With respect to this space, create a position-dependent channel impulse response that is overlaid with distortions. Based on these channel impulse responses, the position must be estimated using particle filters or Kalman filters. In addition to signal processing theory, this includes knowledge of multipath propagation and channel impulse response including spatial aspects of spatial geometry.
- Scientific documentation including the theoretical and experimental background of the scenarios, as well as an evaluation of the simulation results.
- Well documented simulation scripts
Tasks
- Deal with a signal transmission considering multipath propagation, as in Rayleigh or Rice fading channels.
- Develop a simple 2-dimensional spatial geometry in which a position can be determined using a distorted channel impulse response. (Consider line-of-sight, and first and second order reflections).
- Simulate Monte Carlo-based distorted channel impulse responses for an unknown position.
- Estimate this position using particle filters and Kalman filters.
- Evaluate these results and use a self-selected metric to decide the filter that gives the best results
Requirements
- Good knowledge of Matlab programming
- Basic knowledge of wireless transmission (PHY layer)
- Signal processing skills such as particle filters or Kalman filters would be desirable
- Interest in theoretical simulations
- Willingness to learn about signal transmission and processing
- Ability to work independently and in a self-organized manner
- IT security and data protection
Supervisor: Dorina Gumm
Subject area: IT security and data protection are very relevant in product development - because more and more systems have IT components, a lot of data is processed and attack scenarios are becoming more diverse. Strengthening IT security can already be taken into account in the design, through analyzes of existing applications as well as through training. Work in this subject area can therefore be very diverse and have very different goals. 3 main areas are presented here.
Game design for Security and Privacy (GSP)Learning through play: How does cross-site scripting work? How can identity theft occur? How can platform access be secured? Why should communication be encrypted? Develop games that introduce players to security, self-protection and privacy issues.
GSP is about the question of how the above topics can be experienced by means of gamification and thus made accessible to a wider audience. The aim is to promote awareness for these issues in society as well as in companies (digital maturity). If you are interested, you can devote yourself to these topics as part of design and practical projects as well as theses.
Data protection and usability (DU)Data protection is often presented publicly as an inhibitor of innovation that affects the functionality and usability of applications. Is that really the case? How can applications be developed to be privacy-friendly and user-friendly? What mechanisms for anonymization / pseudonymization are there and how can they be taken into account in the design process? Theses can address these questions based on a specific application, e.g. from the work environment.
Security and web applications (SW)The security of web applications is playing an increasingly important role, as web applications often represent the user interface for controlling a wide variety of products. This subject area examines, for example, which security concepts should be taken into account when designing the application or according to which criteria applications should be examined. The theses can be linked to specific product developments or projects.
- Apparatus for self-aligning antennas for establishing point-to-point radio links
Open: Apparatus for self-aligning antennas for establishing point-to-point radio links
Supervisor: Swen Leugner, Horst Hellbrück
Topic
Modern communication systems increasingly use wireless connections. They allow the user more mobility, more convenient data transmission or are more cost-effective than comparable wired connections. Directional radio links, which enable point-to-point communication, still offer great potential. However, due to the directional effect of the antennas, both pairs of antennas must be aligned as precisely as possible in order to exploit the full potential.
Details
The precise alignment of directional radio links requires a lot of time and effort. The aim of this work is to develop a device for the automatic alignment of two directional radio antennas in order to achieve the maximum link budget and thus also the maximum data throughput. The alignment is done horizontally and vertically.
Tasks
- Deployment of the radio link and description of it
- Conceptual design of the device for automatic antenna alignment in vertical and horizontal direction of rotation
- Construction of the automated antenna alignemt apperatus
- Deployment of the automated antenna alignemt apperatus
- Evaluation of the automated antenna alignemt apperatus according to the data throughput
- Documentation of the radio link, automated antenna alignemt apperatus, deployment and evaluation
Requirements
- Confident handling of hardware
- Basic understanding of communications technology, directional radio and antennas
- Basic understanding of programming for programming the apperatus
- Good understanding of and experience with CAD software
- Independent and organised way of working
- Engagement
Completed bachelor's, master's and student research projects
- List of projects completed at CoSA
