Elec. Engineering/Physics/Computer Science Internship/Master Thesis Student (MAC Methods) (m/f/d)

Job Description

Req ID: 6838

Place of work: Oberpfaffenhofen

Starting date: as soon as possible

Career level: Internship, Student research project and final thesis

Type of employment: Full-time, Part time

Duration of contract: 6 months

Remuneration: Remuneration is in accordance with the Collective Agreement for the Public Sector - Federal Government (TVöD-Bund).

Enter the fascinating world of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt e. V.; DLR) and help shape the future through research and innovation! We offer an exciting and inspiring working environment driven by the expertise and curiosity of our 12,000 employees from 100 nations and our unique infrastructure. Together, we develop sustainable technologies and thus contribute to finding solutions to global challenges. Would you like to join us in addressing this major future challenge? Then this is your place!

The DLR Institute of Communications and Navigation is dedicated to mission-oriented research in selected areas of communications and navigation. Its work ranges from the theoretical foundations to the demonstration of new procedures and systems in a real environment and is embedded in DLR's Space, Aeronautics, Transport, Security and Digitalization programmes.

What to expect

Optical satellite links provide high and secure throughput between satellites, ground and air nodes. Coherent optical communication reduces optical satellite link size-weight and power (SWaP) requirements at the cost of hardware complexity when compared against non-coherent communication schemes. To reduce hardware complexity of the coherent optical receivers, parts of the receiver may be shifted into the digital domain using intradyne receivers. The shift in digital domain opens up new possibilities for signal processing at various OSI layers. This task aims to evaluate concepts for medium access control (MAC) for free-space point-to-multipoint optical links and understand their effect on optical waveform design. The MAC methods applied primarily include, but are not limited to, space division multiple access (SDMA) and time division multiple access (TDMA). For verification of the MAC methods, simulation using Python as well as an optical testbed are available to the student. The laboratory setup provided to the student consists of an FPGA evaluation board, which is connected to a host Linux computer via JTAG and UART. The host computer is remotely accessible via SSH.

Your tasks

Perform state-of-the-art review for MAC methods for free-space optical links

Simulate different combinations of MAC methods for free-space optical links

Analyze simulation results and highlight effects on the optical waveform

Select most critical changes to the optical waveform and demonstrate their effects in real-time on an FPGA

Your profile

Good programming skills in Python

Basic programming skills in VHDL

Experience with Vivado, git, tcl, GitLab, CI/CD, Docker, Linux

Hands-on experience with FPGAs

Fundamentals of coherent optical transmitters/receivers

Fundamentals of satellite communication

Fundamentals in medium access control methods

Good English knowledge

Good problem-solving skills

We offer

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.

We look forward to getting to know you!
