Inductive coupling matrix of a multiconductor system for a winding-on-core prototype

Broadband circuit models for electric machines are effective means to understand, predict, and control the phenomenon of conducted Electromagnetic Interference (EMI) from immunity/susceptibility perspective. These models should cover the capacitive and inductive coupling behavior of the component along the frequency range of interest. Circuit models used under generic SPICE simulation softwares ar

Public participation in the 3G infrastructure development in Sweden

The infrastructure for 3G has been under development in Sweden since late 2000. Following from the so called beauty contest four operators within three years were to build competing systems to cover 99,98 percent of the population by the end of 2003, giving the administrative system an extreme challenge. Issues widely debated has been the alleged hazardousness of the electromagnetic radiation from

Prediction of Radio Channels for OFDM by Autoregressive Modeling

This paper presents a prediction algorithm for OFDM radio channels in either time or frequency direction that explores the over sampling of the channel transfer function compared to the maximum Doppler shift and the maximum excess delay. The algorithm derives an autoregressive model utilized for prediction. Pre-filtering of channel estimates are concerned and the prediction approach is appraised a
