Dispersion entropy-based Lempel-Ziv complexity: A new metric for signal analysis

Yuxing Li et al.

Summary: Lempel-Ziv complexity (LZC) is an important metric for detecting dynamic changes in non-linear signals. However, it tends to lose effective information and cannot be applied to real-world signal detection due to its dependence on binary conversion. To address these limitations, a dispersion entropy-based LZC (DELZC) is proposed, which increases class number and reduces information loss through normal cumulative distribution function (NCDF), and replaces binary conversion with dispersive entropy (DE) to capture dynamic changes in time series.

Calibration-free wavelength modulation spectroscopy based on even-order harmonics

Yihong Wang et al.

Summary: This paper presents a novel and rapid calibration-free wavelength modulation spectroscopy algorithm based on even-order harmonics. The algorithm simplifies the process of describing gas absorption spectra by using simple algebraic operations, eliminating the need for time-consuming simulations and line-shape fitting procedures. Experimental validation shows that the algorithm can calculate gas parameters at the millisecond level with a relative error of less than 4%.
