Discriminative learning for neural decision feedback equalizers [PDF]

open access: yes, 2000
In this work new Decision-Feedback (DF) Neural Equalizers (DFNE) are introduced and compared with classical DF equalizers and Viterbi demodulators. It is shown that the choice of an innovative cost functional based on the Discriminative Learning (DL ...

Block Transmissions over Doubly Selective Channels: Iterative Channel Estimation and Turbo Equalization

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
Modern wireless communication systems require high transmission rates, giving rise to frequency selectivity due to multipath propagation. In addition, high-mobility terminals and scatterers induce Doppler shifts that introduce time selectivity. Therefore,

Current-Mode Active-C Phase Equalizers Operated at Low Voltage

open access: yesElectrica, 2016
This paper presents two novel current-mode active-C phase equalizer circuits which are operated at low voltage. Both the proposed circuits employ single DXCCII as an active element, a NMOS transistor operated in the triode region as an active resistor ...

Optical and electrical equalizers for fiber optic links [PDF]

open access: yes, 2017
Optical equalizers and electrical equalizers for a fiber link has been explicitly studied and compared. The results demonstrate that both can improve optical links significantly but optical equalizers can perform better in terms of noise ...

Quantifying the improvement of MMSE equalizers by faster sampling rates [PDF]

open access: yes, 2017
The efficiency of faster than symbol rate sampled MMSE equalizers, which is generally considered as a remedy to time or phase errors, is explicitly analyzed accounting for practical channel conditions and pulse shaping filter.

A Bilevel Equalizer for Large Lithium Ion Batteries

open access: yesBatteries, 2017
Due to variations among the cells, large lithium ion batteries (LIB) such as those in battery energy storage stations (BESS) and electric vehicles (EVs) must have an equalizer (EQU) circuit to balance the cell voltages.

Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]

open access: yes, 2000
We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...

The Performance of Pressure-Exchanger Dividers and Equalizers [PDF]

open access: yes, 1969
Tests are reported which were carried out to establish the performance of pressure-exchanger dividers and equalizers using air as the working fluid. The effects of varying rotor speed, port geometry, and port pressure ratios were explored.

Triangle equalizers - a probabilistic approach, part 1 [PDF]

open access: yes, 2016
An equalizer of a triangle is a line which divides it into two regions having equal areas as well as equal perimeters. Every triangle has at least one and at most three equalizers.
