چکیده

− Recently, a novel approach for the estimation of the residual error parameters of a calibrated vector network analyzer has been proposed. The method is based on a reflection measurement employing a high precision airline terminated by a short. From this measurement the complex valued residual error parameters are calculated utilizing a sophisticated data analysis scheme. In this work the uncertainty associated with the obtained residual error parameters is evaluated. The uncertainty evaluation is performed by applying the GUM S1 approach employing a Monte-Carlo method. Resulting uncertainties arising due to imperfections of the dimensional parameters of the airline are presented.

Robust Wavelet Support Vector Machine for Regression Estimation

As we know, M-estimation as objective function can be used to tackle this problem that the performance of wavelet network (WN) is affected by gross error severely, but its influence function is determined by the absolute value of residual, so a key problem is how to choose initial parameters. In this paper combining robust estimation with wavelet support vector machine (WSVM), a robust wavelet ...
