Stochastic Blind Equalization Based on PDF Fitting using Parzen Estimator (2008)

Marcelino Lázaro, Ignacio Santamaría, Deniz Erdogmus, Carlos Pantaleón, Jose C. Principe

Abstract — This paper presents a new blind equalization approach that aims to force the probability density function (pdf) at the equalizer output to match the known constellation pdf. Quadratic...

A Nonlinear MESFET Model for Intermodulation Analysis Using a Generalized Radial Basis Function Network (2007)

Ignacio Santamaría, Marcelino Lázaro, Carlos J. Pantaleón, Jose A. García, Antonio Tazón, Angel Mediavilla

In this paper we use a Generalized Radial Basis Function (GRBF) network to model the intermodulation properties of microwave GaAs MESFET transistors under dynamic operation. The proposed model...

Marcelino Lázaro, Ignacio Santamaría, Carlos Pantaleón

The design of microwave and millimeter-wave circuits and the increasing integration of hybrid and monolithic circuits has reinforced the need of accurate large and small-signal device models to...

A new EM-based training algorithm for RBF networks (2003)

Marcelino Lázaro, Ignacio Santamaría, Carlos Pantaleón

In this paper, we propose a new Expectation–Maximization (EM) algorithm which speeds up the training of feedforward networks with local activation functions such as the Radial Basis Function (RBF)...

Modeling Nonlinear Power Amplifiers in OFDM Systems from Subsampled Data: A Comparative Study Using Real Measurements (2003)

Luis Vielva, Carlos Pantaleón, Marcelino Lázaro, Jesús Ibáñez, Ignacio Santamaría

A comparative study among several nonlinear high-power amplifier (HPA) models using real measurements is carried out. The analysis is focused on specific models for wideband OFDM signals, which are...
