About Me • OpticCss' erapass

I am Jinzhao Li, a Ph.D. student in Electronic and Electrical Engineering (EEE), majoring in signal processing. I am passionate about the decomposition of multicomponent amplitude-modulated (AM) and frequency-modulated (FM) signals, exploring this domain through the lens of time-frequency analysis, sparse representation, and asymptotic analysis. The core of my research involves designing efficient algorithms for non-stationary signals and adapt these theoretical strengths into real-world wireless sensing solutions. My work finds its representative tracks in micro-Doppler estimation, non-contact vital-sign monitoring, and wireless bridge micro-deformation (structural health) monitoring.

I am always eager to hear from prospective collaborators in non-stationary signal processing and wireless sensing (be it radar, base stations, sonar, or any other physical medium you fancy). Please feel free to drop a question or kick off a discussion on any of the papers, research notes, or blog articles hosted here.

No matter the phase or frequency of your interest and research, let's get in touch!!

About Anecdotes

Why the website called optic-css?

The moniker "optic-css" was conceptualized during my early days of learning, driven by a growing fascination with scientific aesthetics. Just as Cascading Style Sheets (CSS) render diverse colors and structures to the , I aspired to shed new light and bring vibrant perspectives onto scientific domains. Granted, it might sound a bit farfetched!

What is the ultimate goal of my research?

I am trying to make fundamental advances in time-frequency analysis and spectral estimation, aiming at analyzing, decomposing, estimating, and processing nonstationary signals, to facilitate their real-world applications.

Finally, hoping to reveal the relationship between the instantaneous bandwidth (instantaneous amplitude) and the instantaneous frequency, meanwhile the stabilities / multiplicities of these concepts for the mono-component and multi-component entities.
