The dAIEDGE Network of Excellence (NoE) seeks to strengthen and support the development of a dynamic European cutting-edge Artificial intelligence (AI) ecosystem under the umbrella of the European Lighthouse for AI, and to sustain the development of advanced AI. dAIEDGE fosters the exchange of ideas, concepts, and trends on cutting-edge next generation AI, creating links between ecosystem actors to help both the European Commission (EC) and the European Union (EU) and the peripheral AI constituency identify strategies for future developments in Europe. Our main objective is to advance Europe’s innovation and technology base by developing a comprehensive policy and governance approach to AI in order for the EU to become a world leader in innovation in the data economy and its applications.

A new approach to the design of optimum transmultiplexer filter banks for overlapping discrete multitone (ODMT) multicarrier modulation is presented. ODMT has been proposed for use in high-speed data communications over twisted pair copper wires such as digital subscriber lines (DSL), due to its ability to cope well with channel degradations and noise. We propose a new design technique which minimizes the overall interference. We consider the effect of the time domain overlap between successive symbol waveforms by considering each modulation filter as a series of filter components in time. We explicitly incorporate some knowledge of the digital subscriber line channel into our design technique, to account for the effects of time dispersion and frequency distortion. Numerical simulations show that the optimisation of the components in the mixed time-frequency domain leads to an increase in the signal-to-interference ratio of the order of 0.2-0.3 dB.
