Ultrawideband signals constructed from Generalized Weyl-Heisenberg bases

Abstract

One type of UWB modulation is multiband-based and is accomplished by using multicarrier or OFDM. In the media with time-frequency dispersion well-localized bases ensure the best signal reconstruction. Generalized Weyl-Heisenberg bases structure, construction and optimization are considered. Presented modeling results confirm good localization characteristics for optimal parameters. This article presents the research work related to the development of enhanced modulation technique with Orthogonal Time-Frequency Division Multiplexing (OFTDM).
