Digital & Embedded Signal Processing

The Digital and Embedded Signal processing group is concerned with the development of digital (sub) systems for radio astronomy applications. The required DESP competences are in the field of digital embedded signal processing: design and development of DSP systems, chip design, signal integrity studies, algorithms and modeling.

The aim of the DESP group is to develop advanced digital signal processing (DSP) systems for the next generation of radio telescopes. Having developed DSP systems for the LOFAR telescope in the Netherlands, our current focus is on technological developments for the SKA telescope and its pathfinders.

LOFAR and previous project systems were developed specifically tailored to the application. Currently we are developing digital which can be used for multiple applications by exploiting the commonalties in the systems we develop. Our long-term goal is to have digital systems already on the shelf before applications are asking for it. In this way we try to improve the turnaround time of projects and stay ahead of what is required by the applications. From application driven design to platform driven design.

In order to facilitate this approach more, we constantly try to improve our design methodology such that we can re-use firmware and work over multiple generations of platforms by adopting modular design and automatic code generation.
