Augmented Lagrangians with adaptive precision control for quadratic programming with equality constraints: Corrigendum and addendum
(Kluwer Academic PublDordrechtHolanda, 2002)
Avoiding Divergence in the Shalvi-Weinstein Algorithm
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
The most popular algorithms for blind equalization are the constant-modulus algorithm (CMA) and the Shalvi-Weinstein algorithm (SWA). It is well-known that SWA presents a higher convergence rate than CMA. at the expense ...
A Class of Channels Resulting in Ill-Convergence for CMA in Decision Feedback Equalizers
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper analyzes the convergence of the constant modulus algorithm (CMA) in a decision feedback equalizer using only a feedback filter. Several works had already observed that the CMA presented a better performance than ...
Equalização neural aplicada a sistemas com modulação bidimensional em fibra óptica
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2014-02-28)
Nowadays, optic fiber is one of the most used communication methods, mainly due to
the fact that the data transmission rates of those systems exceed all of the other means of
digital communication. Despite the great ...
A regional multirnodulus algorithm for blind equalization of QAM signals: Introduction and steady-state analysis
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
It is well known that constant-modulus-based algorithms present a large mean-square error for high-order quadrature amplitude modulation (QAM) signals, which may damage the switching to decision-directed-based algorithms. ...
