For the poor adaptive capability and de-nosing effect of wavelet de-nosing for partial discharge detection in XLPE cable, a wavelet de-nosing algorithm based on Chaotic simulated annealing was proposed to improve adaptive soft threshold value. And then we verify its validity. The algorithm combined Global Chaos rough search with local simulated annealing fine search. This algorithm employs generalized...
The normal-inverse model arises as a normal variance-mean mixture with an inverse Gaussian mixing model. The resulting model, it is very complicated to obtain the influence measures based on the tradition method. In the present paper, several diagnostic measures for outlier data mining are obtained based on the conditional expectation of the complete-data log-likelihood function based on the EM algorithm...
Generalized Hammerstein models can be used to accurately mimic the dynamic nonlinear behaviors of RF power amplifiers or transmitters. A high efficient parameter extraction algorithm for the generalized Hammerstein model is an essential problem for implementing the nonlinear model in a cheap microprocessor. In this paper, a modified systolic array based QRD-RLS algorithm, which is suitable for implementing...
Systolic array is a hardware implementation of fast speed signal and data process using parallel pipeline method. The first systolic implement of QRD-RLS algorithm presented by Gentleman and Kung in 1981, is only suitable to solve the linear problem. In this paper, we will present how to use modified systolic array based QRD-RLS algorithm to identify the model parameters of the memory polynomial nonlinear...
