1	A NEW CORRENTROPY BASED TDE METHOD UNDER α-STABLE DISTRIBUTION NOISE ENVIRONMENT显示文摘This paper presents a robust time delay estimation algorithm for the α-Stable noise based on correntropy. Many time delay estimation algorithms derived for impulsive stable noise are based on the theory of Fractional Lower Order Statistics (FLOS). Unlike previously introduced FLOS-type algorithms, the new algorithm is proposed to estimate the time delay by maximizing the generalized correlation function of two observed signals needing neither prior information nor estimation of the numerical value of the stable noise's characteristic exponent. An interval for kernel selection is found for a wide range of characteristic exponent values of α-Stable distribution. Simulations show the proposed algorithm offers superior performance over the existing covariation time delay estimation, least mean p-norm time delay estimation and achieves slightly improved performance than fractional lower order covariance time delay estimation at lower signal to noise ratio when the noise is highly impulsive.

2	Narrowband time delay estimation based on correlation coefficient显示文摘The problems of time delay estimation of narrowband signals are presented.The disadvantages of the existing algorithms are analyzed,and a new narrowband time delay estimating algorithm based on correlation coefficient is proposed.The original time delay information is transfered into the delay between the autocorrelation and cross-correlation function,and the precise estimating result by wave-comparison is given.The algorithm proposed here is also compared with other algorithms and its advantages over other algorithms are proved.The theoretical analysis and simulation show the effectiveness of the proposed algorithm.

3	New HB-weighted time delay estimation algorithm under impulsive noise environment显示文摘The traditional HB-weighted time-delay estimation (TDE) method degenerates under the impulsive noise environment.Two new time-delay estimation methods are proposed based on fractional lower order statistics (FLOS) according to the impulsive characteristics of fractional lower order a-stable noises.Theoretic analysis and computer simulations indicate that the proposed covariation based HB weighted (COV-HB) algorithm can suppress impulsive noises in one received signal for 1≤α≤2,whereas the other proposed fractional lower order covariance- based HB weighted (FLOC-HB) algorithm has robust performance under arbitrary impulsive noise conditions for the whole range of 0<α≤2.

4	Transportation of dynamic biochemical signals in non-reversing oscillatory flows in blood vessels显示文摘Biological processes and behaviors of endothelial cells on the inner surfaces of blood vessels are regulated by the stimulation from biochemical signals contained in the blood.In this paper,the transportation of dynamic biochemical signals in non-reversing oscillatory flows in blood vessels is analyzed by numerically solving a nonlinear governing equation for the time-dependent Taylor-Aris dispersion.Results show that the nonlinear frequency-amplitude modulation of the transportation of biochemical signals is more(less) significant when the frequency of an oscillatory flow is close to(higher than) that of an oscillatory signal.Under steady flow,the transfer function for the signal transmission system is obtained,showing that the system is a low-pass filter.Lower inner radius or higher center-line velocity of a blood vessel increases the cutoff frequency of the transportation system.These results suggest the possibility and condition for the 'remote' transmission of low-frequency dynamic biochemical signals in pulsatile blood flows.
