Generalized Minimum Error Entropy for Adaptive Filtering [PDF]

open access: yes, 2023
Error entropy is a important nonlinear similarity measure, and it has received increasing attention in many practical applications. The default kernel function of error entropy criterion is Gaussian kernel function, however, which is not always the best ...

Control on 3-D Fixable Wing Flutter Using an Adaptive Neural Controller [PDF]

open access: yesEngineering and Technology Journal, 2012
An adaptive neural controller to control on flutter in 3-D flexible wing is proposed. The aeroelastic model was based on the coupling between structure-of the equivalent plate (wing) and the aerodynamic model that is based on a hybrid unsteady panel ...

Performance of Multihop Wireless Links over Generalized-K Fading Channels [PDF]

open access: yes, 2010
The performance of multihop links is studied in this contribution by both analysis and simulations, when communicating over Generalized-K (KG ) fading channels. The performance metrics considered include symbol error rate (SER), outage probability, level

Generalized Additive Models with Unknown Link Function Including Variable Selection [PDF]

open access: yes, 2013
The generalized additive model is a well established and strong tool that allows to model smooth effects of predictors on the response. However, if the link function, which is typically chosen as the canonical link, is misspecified, substantial bias is ...

High mobility channel estimation method based on improved basis expansion model

open access: yesDigital Communications and Networks, 2019
In this paper, the problem of high mobility channel estimation in the Long-Term Evolution for Railway (LTE-R) communication system is investigated. By using a Basis Expansion Model (BEM), the channel impulse response is modeled as the sum of several ...
