FFT multi-frequency synthesizer

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
An fast-Fourier-transform (FFT)-based procedure which synthesizes the waveform directly from the set of spectral components is presented. A Gaussian window function is introduced to deal with noninteger frequencies. There exists an optimal condition for the width of the window which minimizes the numerical error. Techniques for the generation of linear

Hybrid Observer for multi-frequency signals

IFAC Proceedings Volumes, 2010
Abstract We proposed a hybrid observer to estimate the frequencies of a signal even in the presence of saturation. Semi-global exponential convergence of the estimation error is provided, and the problem of retrieve dynamically the angular frequencies is addressed.

UniTag: Enabling Multi-Frequency Backscatter

GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020
In this paper, we for the first time demonstrate how to realize multi-frequency backscatter communication for low power IoT devices. Our key innovation is an encoding rule that works from O(100) MHz to 2.4 GHz to cover most commercial communication bands such as BLE, LoRa and Wi-Fi.

Multi-frequency rapid-scan HFEPR

Journal of Magnetic Resonance, 2018
Gaining access to electron spin dynamics at (sub-)THz frequencies is highly challenging. However, this information is highly relevant for the understanding and development of spin polarization agents in dynamic nuclear polarization methods and single-molecule magnets for quantum computation.
