Diversity Analysis of Symbol-by-Symbol Linear Equalizers
, 2011 In frequency-selective channels linear receivers enjoy significantly-reduced complexity compared with maximum likelihood receivers at the cost of performance degradation which can be in the form of a loss of the inherent frequency diversity order or ...

EURASIP 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,

A Bilevel Equalizer for Large Lithium Ion Batteries
Batteries, 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.

Classical and Bayesian Linear Data Estimators for Unique Word OFDM
, 2012 Unique word - orthogonal frequency division multiplexing (UW-OFDM) is a novel OFDM signaling concept, where the guard interval is built of a deterministic sequence - the so-called unique word - instead of the conventional random cyclic prefix.
