Self-Iterating Soft Equalizer

open access: yes, 2013
A self-iterating soft equalizer (SISE) consisting of a few relatively weak constituent equalizers is shown to provide robust performance even in severe intersymbol interference (ISI) channels that exhibit deep nulls and valleys within the signal band ...

ISI Cancellation Using Blind Equalizer Based on DBC Model for MIMO-RFID Reader Reception [PDF]

open access: yes, 2015
Under the dyadic backscatter channel (DBC) model, a conventional zero forcing (ZF) and minimum mean square error (MMSE) method for MIMO-RFID reader reception are not able to be rapidly cancelled inter-symbol interference (ISI) because of the error of ...

Low Complexity MLSE Equalization in Highly Dispersive Rayleigh Fading Channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
A soft output low complexity maximum likelihood sequence estimation (MLSE) equalizer is proposed to equalize M-QAM signals in systems with extremely long memory. The computational complexity of the proposed equalizer is quadratic in the data block length

A Bilinear Equalizer for Massive MIMO Systems

open access: yes, 2018
We present a novel approach for low-complexity equalizer design well-suited for cellular massive MIMO systems. Our design allows to exploit the channel structure in terms of covariance matrices to improve the performance in the face of pilot ...

Inter-track interference mitigation with two-dimensional variable equalizer for bit patterned media recording

open access: yesAIP Advances, 2017
The increased track density in bit patterned media recording (BPMR) causes increased inter-track interference (ITI), which degrades the bit error rate (BER) performance.

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.
