Sign Data Derivative Recovery [PDF]

open access: yesISRN Applied Mathematics, 2012
Given only the signs of signal plus noise added repetitively or sign data, signal amplitudes can be recovered with minimal variance. However, discrete derivatives of the signal are recovered from sign data with a variance which approaches infinity with decreasing step size and increasing order.

Design of a DVI video receiver chip

open access: yesDianzi Jishu Yingyong, 2022
In this paper, a DVI(Digital Visual Interface) receiver chip is designed and an all-digital-based T.M.D.S signal reception recovery scheme is proposed. This scheme can greatly reduce the design difficulty of PLL and the hardware overhead of the chip.This

A constrained-based optimization approach for seismic data recovery problems [PDF]

open access: yes, 2014
Random and structured noise both affect seismic data, hiding the reflections of interest (primaries) that carry meaningful geophysical interpretation. When the structured noise is composed of multiple reflections, its adaptive cancellation is obtained ...

Length and curvature variation energy minimizing planar cubic G1 Hermite interpolation curve

open access: yesJournal of Taibah University for Science, 2020
In this paper, we study how to construct a planar cubic G1 Hermite interpolation curve with minimal length and curvature variation energy. This problem is solved by a bi-objective optimization model.

Experimental Verification of Human Body Communication Path Gain Channel Modeling for Muscular-Tissue Characteristics

open access: yesIEEE Access, 2019
To study the signal transmission mechanism in the human body, the channel characteristics are generally analyzed by modeling. In current modeling methods, the human body is considered quasi-static and the human tissues isotropic, for simplifying the ...
