时差估计算法 Basic aspects of time delay estimation (TDE) based on sampled,signals are investigated in this paper. The direct cross-correlation method is analyzed and compared to the average square difference function (ASDF) and the (addition only based)
Multifractal detrended cross-correlation analysis for two nonstationary signals,周炜星,,It is ubiquitous in natural and social sciences that two variables, recorded temporally or spatially in a complex system, are cross-correlated and possess multifract
Considering a single-mode laser system with cross-correlated additive colored noise and multiplicative colored noise, we study the effects of correlation among noises on the normalized intensity correlation function C(s). C(s) is derived by means of
For two odd integers l; k with 0 < l < k and gcd(l; k) = 1, let m = 2k and d = (2^{lk}+1)/(2^l+1). In this paper, we study the cross-correlation between a binary m-sequence (st) of length 2^m-1 and its d-decimated sequences (s_{dt+u}); 0<=u
The stochastic resonance (SR) of an optical bistable system with cross-correlated additive white and multiplicative colored noises and periodic signal is studied using the unified colored noise approximation and the theory of signal-to-noise ratio (S
A single-mode laser system with colored cross-correlated additive and multiplicative noise terms is considered. By the means of projection operator method, we study the effects of the cross-correlation time 'tau' and the cross-correlation intensity '
The cross-correlation method for temporal characterization is investigated using simulations of the twocolor above threshold ionization (ATI) on He induced by a vacuum ultraviolet (VUV) free-electron laser (FEL) in the presence of an infrared (IR) fi
Synthetic aperture ultrasonic imaging is currently widely used in railway, aviation, automobile manufacturing and petrochemical, major in non-destructive testing the defects of key components and materials, and showing them in form of image. Due to i
