Analysis of the Rician K Factor in a Typical Millimeter-Wave Office Scenario

Rubio Arjona, Lorenzo; Rodrigo Peñarrocha, Vicent Miquel; Reig, Juan; Fernandez, H; Pérez, Jesus R.; Torres, Rafael P.; Valle, Luis (Institute of Electrical and Electronics Engineers, 2024-05)

[EN] In this letter, the K-factor is estimated in a typical office scenario based on wideband channel measurements carried out at millimeter-wave (mmWave) frequencies, covering the 25-40 GHz spectrum, in both line-of-sight ...
Classification of paroxysmal and persistent atrial fibrillation in ambulatory ECG recordings

Alcaraz, Raúl; Sandberg, Frida; Sornmo, Leif; Rieta Ibañez, José Joaquín (Institute of Electrical and Electronics Engineers (IEEE), 2011-05)

The problem of classifying short atrial fibrillatory segments in ambulatory ECG recordings as being either paroxysmal or persistent is addressed by investigating a robust approach to signal characterization. The method ...
Comparative study of speed estimators with highly noisymeasurement signals for Wind Energy Generation Systems

Carranza Castillo, Oscar; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel; González Morales, Luis Gerardo (Elsevier, 2011-03)

This paper presents a comparative study of several speed estimators to implement a sensorless speed control loop in Wind Energy Generation Systems driven by power factor correction three-phase boost rectifiers. This rectifier ...
Instantaneous Frequency of the Left Sideband Harmonic During the Start-Up Transient: A New Method for Diagnosis of Broken Bars

Pineda-Sanchez, Manuel; Riera-Guasp, Martín; Antonino-Daviu, J.; Roger-Folch, José; Perez-Cruz, Juan; Puche-Panadero, Rubén (Institute of Electrical and Electronics Engineers, 2009)

[EN] In this paper, a new method for detecting the presence of broken rotor bars is presented. The proposed approach is valid for induction machines started at constant frequency and consists of extracting the instantaneous ...
