Christening our First Boat

On July, 19th we christened our (first) small ship. It got the name "MISSy", which stands for "MIMO SONAR System". We did this at the "Kitzeberger Strand". Beside having a small party due to the event, we also did several measurements. One of them was testing a first version of our underwater telephone system. One subscriber was located at the pier, while the second one were Thorben and Alexej cruising with MISSy about 100 to 200 m in front of the pier. We had quite good signal quality, even when operating in so-called full-duplex mode (both subsribers can talk simultaneously). Several people tested the phone - even very young ones, as you can see on the picture.

Thanks again to all people who helped us to let MISSy see finally the water (Matthias, Martin, Dietmar, Jan, and all the others).

New Low-delay Audio Hardware

Anton and Alexej are ready now with the preparation of our new low-delay hardware for our embedded lab. The hardware, so-called bela boards, can handle up to 10 inputs and 10 outputs and can operate with a round-trip delay of about 1 ms. The boards are programmed in C/C++ and allow for very "nice" audio examples.

Currently we implement speech enhancement algorithms, anti-noise systems, and virtual reality approaches (in terms of "audio-only reality") as student projects using the boards.

If you are interested, have a look on the website of our new embedded lab that will start in the winter term 2018/2019.

Philipp is now "Doc Bulling"

On Monday, 10th of September 2018, Philipp Bulling sucessfully defended his dissertation on speech enhancement for in-car communication systems. His work focused mainly on the control of adaptive feedback cancellation filters (details can be found here). After an excellent talk Philipp gave very good answers to the questions of the committee and at around 11:30 h everythings war over and we had a small celebration (thanks also to Philipp's parents for preparing that part of the defense). An finally of course: contratulations to Philipp - very well done!

Summer Event 2018

Last Friday we clebrated our yearly summer event in combinantion with the summer meeting of the Gesellschaft für angewandte Signalverarbeitung e.V. First, the year was reviewed from the perspective of the professors (talk from Gerhard Schmidt), the Ph.D. students (talk from Finn Spitz), and the bachelor and master students (talk from Jonas Weiss and Alexander Wilbrandt). Afterwards Eric Elzenheimer (as beeing member of the executive Committee of GaS e.V.) handed over the price for the best thesis in the area of applied signal processing to Tobias Klawonn (congratulations once again). Finally, Michael Klein from the company Berner talked to the audience before we had our yearly barbecue and our get-together. This year also the weather was really nice, allowing us to stay outside until late night.

> Hello World.

Congratulations to Wiebke and Marco to their first baby. We don't want to share too much information about size and weight of young Jonte, since it has something of this card game "Quartett" that we played in our youth. Anyhow, we were pretty impressed by both numbers!

One sentence about the title of this article: it's hard to see in the picture, but we ordered rompers for Jonte with the letters "> HELLO WORLD." on it. We are engineers, sorry.

Marco and Wiebke, enjoy now the time with little Jonte - we wish all three of you all the best.

TensorFlow and Escape Rooms

The last two days (Monday and Tuesday, September 16 and 17, 2019), the whole DSS team did a course on TensorFlow and Keras. Since we already have interfaces of TensorFlow to our real-time tool KiRAT, it was time now to extend our knowledge on graphs and the corresponding training of weights, biases, etc. After two days of hard work we booked two escape rooms and solved the "secrets" hidden in ...
