WebMay 4, 2008 · We exploit a first-order recursion method with time-frequency varying smoothing coefficients to accurately estimate a noise power spectral density (PSD) in both slowly and rapidly varying regions. WebApr 1, 2005 · The paper presents a simple recursive solution to passive tracking of maneuvering targets using time difference of arrival (TDOA) measurements. Firstly, an iterative Gauss–Newton algorithm is developed for stationary target localization based on a constrained weighted least-squares (CWLS) criterion. The advantages of the CWLS …

WebJan 28, 2011 · The method consists of recursively smoothing and filtering the input time series using moving quantiles. It uses a sequence of window widths and quantiles, and starts by filtering the time series using the first window width and quantile in the specified sequences. The second filter is applied to the output of the first one, using the second ...

WebMay 1, 2009 · Introduction This paper axiomatizes and investigates a model of recursive preferences over intertemporal plans, extending the smooth ambiguity model developed … WebJan 18, 2024 · Peridynamic smoothing can be used to remove or minimize noise in the data. Also, it can be used to smooth the local discontinuities which emerge during the regression process in a recursive manner. 4.6.1 Noise Removal. The PD smoothing for noise removal is demonstrated by considering the noisy data shown in Fig. 4.23. It includes 10,000 data ... Exponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. It is an easily learned and easily applied procedure for making some determination based on prior assumptions by the user, such as seasonality. Exponential smoothing is often used for anal… flower boy wallpaper laptop
