Resumé:
In recent years the emergence of various broadband appications and the proliferation of mobile phones have resulted in increased demand of ultra-high data rates. Multicarrier techniques and in particular OFDM (orthogonal freqency division multiplexing) are widely used in wired used in wired and wireless communications systems, thanks to their spectral efficiency and robustness against frequency selective channels. However, performance and efficiency decrease in time selective channels (e.g. mobility scenario). First the fundamental performance limits of time-frequency and very selective broadband channels will be studied. Then, theoretical solutions to reach these limits using methods based on linear canonical transformation and time-frequency analysis will be proposed. Finally, end-to-end optimization of communication systems based on the proposed techniques will be performed, exploring as well as the potential of using machine learning in this setting.
