Welcome to the Institute of Digital Signal Processing!

Think complete.

The motto Think complete. represents our ambition to span DSV’s research from algorithms to prototypes with the ultimate goal to invent technical feasible solutions for challenging real-world scenarios.


The challenges

For instance, finding forgotten objects in our living environments by a simple “App” on our smartphone is today an unsolved technical challenge. One principal solution being capable for mass market introduction is to enrich our daily objects with passive RFID tags, but the coverage of nowadays passive RFID tags is severely limited; in particular, a “through-the-wall” detection of such passive RFID tags is seemingly impossible. Our approach for solving this challenging real-world scenario is to significantly extend the coverage by merging advances in RFID technology with sophisticated signal processing techniques, e.g. by using multiple antennas being well-known from cellular communications. Our general methodology is as follows: after drafting basic algorithms, we investigate its performance by extensive simulations. Then, we carry out measurements, typically in an indoor environment, for validating the simulations and, if sufficiently promising, we embed such suitable signal processing on programmable digital signal processors being used in mass market devices. Last but not least, we build up software configurable prototypes in order to practically demonstrate the achievable performance and its proper operation. And of course, then the refinement starts ...


The Research Groups

All these four fundamental steps are covered by four corresponding research groups: the fundamental algorithm invention by the “Algorithm Design and Analysis (ADA) Group”, the comprehensive algorithm validation by the “System Simulation and Measurement (SSM) Group”, the efficient algorithm implementation by the “Embedded Signal Processing (ESP) Group”, and the flexible prototyping by the “Software Configurable Platform and Prototyping (SCPP) Group”.


The 4 P's

Last but not least, Think complete. also means to cover all the “4 P’s”: Papers, Patents, Prototypes … and, in particular, the thinking towards Products. Especially the latter drives us to spin-off our ideas and expertise into companies – the final step towards filling the needs of our society by solving challenging real-world scenarios.
