Fast Convolution without Additional Delay

written by Gerhard Schmidt, Anton Namenas, and Seedo Eldho Paul

The section is currently in progress ...

Code Example

As usual you can find below some matlab code that shows a comparison between a pure time-domain convolution and the described mixed-domain convolution.

Basic Idea of RED

RED (robust and efficient DSP) is a collection of algorithms that should help engineers to implement basic signal processign tasks in - as the name states - a robust and efficient way. This includes mainly numerical aspects.

Here you can find the chapter on fast convolution without additional delay as a single pdf file. If you would like to download all chapters please go to the RED overview page and get the pdf document that contain all chapters from there.

Aylin Kösker Presented her Bachelor Thesis at DAGA 2026

In March 2026, the DSS Chair attended the annual DAGA conference in Dresden. Thanks to the support of the GaS-Club, the student Aylin Kösker was given the opportunity to accompany the chair and participate in the conference from March 23rd to March 26th. As part of the daily poster sessions, she presented the results of her bachelor’s thesis “Machine Learning for the Analysis of Hydrographic Data to Assess the Waterside Accessibility of Port Waters” in the field of Underwater Acoustics. The thesis forms an important basis for an ongoing university research project on the acoustic analysis of sediment properties in harbor areas. The poster session enabled valuable discussions with researchers and conference participants from related research fields.
