Dehghan Firoozabadi, Ali; Irarrázaval, Pablo; Adasme, Pablo; Zabala Blanco, David; Palacios Játiva, Pablo Geovanny; Azurdia Meza, César (MDPI, 2020)Sound source localization is one of the applicable areas in speech signal processing. The main challenge appears when the aim is a simultaneous multiple sound source localization from overlapped speech signals with an ...

Dehghan Firoozabadi, Ali; Irarrázaval, Pablo; Adasme, Pablo; Zabala Blanco, David; Azurdia Meza, César (Springer, 2020)The aim of this article is estimating the number of simultaneous speakers from the overlapped speech signals. The percentage of correct number of speakers is an important factor for the proposed algorithm. The proposed ...

Zabala Blanco, David; Azurdia Meza, César; Montejo Sánchez, Samuel; Dehghan Firoozabadi, Ali (Optical Society of Japan, 2020)It is well known that the performance of orthogonal frequency division multiplexing (OFDM) is limited by phase noise, which depends on the laser linewidths for coherent-detection radio over fiber (RoF) systems. In this ...

Unsupervised method for correlated noise removal for multi-wavelength exoplanet transit observations Dehghan Firoozabadi, Ali; Díaz, Alejandro; Rojo Rubke, Patricio; Soto, Ismael; Mahú Sinclair, Rodrigo; Becerra Yoma, Néstor; Sedaghati, Elyar (IOP Publishing, 2017-07-01)Exoplanetary atmospheric observations require an exquisite precision in the measurement of the relative flux among wavelengths. In this paper, we aim to provide a new adaptive method to treat light curves before fitting ...
