Scholar-generated biography
Henri Nussbaumer is a researcher specializing in signal processing and digital filtering. His work focuses on developing efficient algorithms for discrete Fourier transforms (DFT), convolutions, and polynomial transforms. He has contributed to the design of fast Fourier transform (FFT) techniques, including reduced-operation algorithms and applications in digital filtering. His research also covers number theoretic transforms, such as Fermat number transforms and pseudo Fermat number transforms, for use in communication systems. Additionally, he has explored methods for voice signal coding and fault detection in communication protocols. His publications highlight the application of polynomial transforms in multidimensional DFTs and digital filtering systems.
