摘要

一种UWB调制是基于多频带的，通过使用多载波或OFDM来实现。在具有时频色散的介质中，定位良好的基确保了最佳的信号重构。研究了广义Weyl-Heisenberg基的结构、构造和优化问题。建模结果证实了最优参数具有良好的局部化特性。本文介绍了正交时频分复用(OFTDM)增强调制技术发展的相关研究工作。

Ultrawideband signals constructed from Generalized Weyl-Heisenberg bases

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).
