Master Thesis in Communication Systems

Available internal projects

These projects are related to one of our current research projects and you will work in close collaboration with our faculty and Ph.D. students. To apply for an internal project, please send an email to the contact person for the project, and include a short description of yourself and a grade transcript. Generally, students applying for internal projects must have a strong background in mathematics and good skills in computer programming. Some knowledge of hardware is useful for some of the projects.
