The performance of microwave photonic signal processors based on microcombs with different input signal waveforms [PDF]
MDPI Photonics Volume 10, 10111283 (2023)Microwave photonic (MWP) signal processors, which process microwave signals based on pho-tonic technologies, bring advantages intrinsic to photonics such as low loss, large processing bandwidth, and strong immunity to electromagnetic interference. Optical microcombs can offer a large number of wavelength channels and compact device footprints, which ...

Uniform attribute-content model
The Journal of Engineering, 2019 There have been growing needs for text processing, such as classifying, retrieving and clustering. The foundation of such a process is to extract features, which can best describe the text. Great progress has been made in text modelling. However, most of

Signal denoising based on the Schrödinger operator's eigenspectrum and a curvature constraint [PDF]
arXiv, 2019 Recently, a new Signal processing method, named Semi-Classical Signal Analysis (SCSA), has been proposed for denoising Magnetic Resonance Spectroscopy (MRS) signals. It is based on the Schr\"odinger Operator's eigenspectrum. It allows an efficient noise reduction while preserving MRS signal's peaks.
