Triangular Phase Shift Detector for Drone Precise Vertical Landing RF Systems

Autor: Pedro J. Quintana-Morales, Francisco Cabrera-Almeida, Eugenio Jimenez-Yguacel, Victor Arana-Pulido

Publikováno v: IEEE Transactions on Instrumentation and Measurement. 70:1-8

This article presents a circuit for the precise vertical landing of drones based on a three phase-shifts detection of a single frequency transmitted from the landing point. The circuit can be considered as a new navigation sensor that assists in guid

In this paper the permutation entropy (PE) obtained from heart rate variability (HRV) is analyzed in a statistical model. In this model we also integrate other feature extraction techniques, the cepstrum coefficients derived from the same HRV and a s

A new DOA estimation algorithm for ARMA sources applied to sperm-whale localization

Autor: Eduardo Hernández-Pérez, S. Martin-Gonzalez, Antonio G. Ravelo-García, Pedro J. Quintana-Morales, Juan L. Navarro-Mesa

Publikováno v: SAM

We present a new method for DOA estimation that relies on the assumption that the sources can be modelled as ARMA. A matrix formulation is introduced in the frequency domain so that the available information from the sources can be incorporated thus

A Boosting Method with Gaussian Mixtures as Base Learners in a Low-Dimension Space

Autor: Juan L. Navarro-Mesa, Antonio G. Ravelo-García, Pedro J. Quintana-Morales, Eduardo Hernández-Pérez, S. Martin-Gonzalez, F. D. Lorenzo-García

Publikováno v: 2006 16th IEEE Signal Processing Society Workshop on Machine Learning for Signal Processing.

In this paper we propose a classification method in the context of Boosting called Transformed Space Boosting (TSB). Our aim is to develop the idea of using a combination of Gaussian Mixture Models and transformation matrices to design `non-weak' bas

A Chernoff ASED Approach to the Estimation of Transformation Matrices for Binary Hypothesis Testing

Autor: S. Martin-Gonzalez, Pedro J. Quintana-Morales, Juan L. Navarro-Mesa, F. D. Lorenzo-García, Antonio G. Ravelo-García, Eduardo Hernández-Pérez

Publikováno v: ICASSP (5)

We present a new method for improving the classificacation score in the problem of binary hypothesis testing where the classes are modeled by a Gaussian mixture. We define a cost function which is based on the Chernoff distance and from it a transfor

Modified realizable frequency warped ARMA modeling and its application in synthesis structures for voiced speech

Autor: Juan L. Navarro-Mesa, Pedro J. Quintana-Morales

Publikováno v: INTERSPEECH

Synthesis filters are of major concern in many speech applications. In this paper these filters are designed so as to track the natural variations, parameterize the perceptually relevant aspects of the pole and zero characteristics and their dynamics

Frequency warped ARMA analysis of the closed and the open phase of voiced speech

Autor: Pedro J. Quintana-Morales, Juan L. Navarro-Mesa

Publikováno v: INTERSPEECH

Frequency-warped analysis techniques are attractive in many speech applications since they have a clear connection to human hearing. In this paper we propose a warped version of a pole-zero analysis obtained from several periods of voiced speech. We
