| Lernergebnisse und erworbene Kompetenzen | After completing this module, the students are able to understand the fundamental concepts of adaptive filters and array signal processing. These concepts include the mathematical background, in particular concepts and "tricks" that can be used for the derivation of new research results. Furthermore, they range from adaptive temporal and spatial filters to (multi-dimensional) high-resolution parameter estimation techniques and tensor-based signal processing concepts. The students have a deep understanding of these universal (timeless) principles that are applicable in several research areas and disciplines. The students are enabled to read and understand current research publications in the areas of adaptive filters and array signal processing. They are able use these concepts and results for their own research and understand the presentations about these topics at international conferences. Furthermore, they are able to read and understand current IEEE journal and conference publications in this area. Moreover, they have been enabled to develop new research ideas and results that build on this published "state-of-the-art." |
