According to the algorithms based on Gaussian assumption are not accurate due to the presence of non-Gaussian signals and noise in the real environment. In this paper, a non-Gaussian noise model based on alpha stable distribution is set, and a time-delay estimation algorithm based on fractional lower order statistics is studied, where fractional lower order covariance matrix makes the time-delay estimation...
The influence of topography on land-surface bidirectional reflectance and albedo should be considered in rugged terrain. However, land-surface albedo algorithms neglect topographic effects, leading to errors in estimating the albedo in rugged terrain. This letter investigates the Angular Bin (AB) algorithm of land-surface albedo and shows that it should be improved when albedo is estimated in rugged...
With the development of nonlinear science, the existence of long memory in the financial market volatility has been found, which is inconsistent with the weak form of Efficient Market Hypothesis. With the brief introduction of Heterogeneous Market Hypothesis and Fractal Market Hypothesis, the long memory behavior of Shanghai Stock Index's returns volatility is tested, based on H/S analysis and GPH...
