Software Defined Radio implementation of receiver digital signal processing algorithms

Starting date

1 September 2021

Duration of contract

6 months


up to German TVöD 5

Type of employment


In the last few years the Internet of Things (IoT) paradigm has arisen in communications: a massive number of devices need to communicate via a wireless medium to deliver (sporadically) small data units to a common gateway. At DLR, solutions based on advanced random access schemes employing both strong error-correcting codes and multi-user detection techniques have been designed, analyzed and tested mainly through simulations. Since in the past decades general purpose computers have made huge leaps in both computing power and memory size, thus implementing radio communication blocks in software has become an attractive solution for going beyond simulations and move towards prototyping computationally intensive communication algorithms.

The internship’s purpose is to design and implement digital signal processing blocks on an existing software defined radio (SDR) framework. In particular, the focus lies on adapting, simulating and implementing existing receiver algorithms (or design new ones) for timing acquisition, carrier frequency and phase estimation, channel estimation under various performance constraints. The internship offers a valuable opportunity to get a deep understanding about the interplay of computer science and communications engineering by studying an existing SDR framework employed in a live setup with real radio frontends.

Your qualifications:

  • Study of Electrical Engineering, Communication Engineering,
  • Computer Science or similar
  • Hands on experience in C/C++, a scripting language (e.g. MATLAB, Python), Linux
  • and collaboration tools (e.g. git, svn)
  • Layer 1 (PHY) basic knowledge is advantageous

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
