Fast Channel Estimation in the Transformed Spatial Domain for Analog Millimeter Wave Systems
Sandra Roger, Maximo Cobos, Carmen Botella-Mascarell +1
Fast channel estimation in millimeter-wave (mmWave) systems is a fundamental enabler of high-gain beamforming, which boosts coverage and capacity. The channel estimation stage typi…
Listen carefully and tell: an audio captioning system based on residual learning and gammatone audio representation
Sergi Perez-Castanos, Javier Naranjo-Alcazar, Pedro Zuccarello +1
Automated audio captioning is machine listening task whose goal is to describe an audio using free text. An automated audio captioning system has to be implemented as it accepts an…
Anomalous Sound Detection using unsupervised and semi-supervised autoencoders and gammatone audio representation
Sergi Perez-Castanos, Javier Naranjo-Alcazar, Pedro Zuccarello +1
Anomalous sound detection (ASD) is, nowadays, one of the topical subjects in machine listening discipline. Unsupervised detection is attracting a lot of interest due to its immedia…
Acoustic Scene Classification with Squeeze-Excitation Residual Networks
Javier Naranjo-Alcazar, Sergi Perez-Castanos, Pedro Zuccarello +1
Acoustic scene classification (ASC) is a problem related to the field of machine listening whose objective is to classify/tag an audio clip in a predefined label describing a scene…
Time Difference of Arrival Estimation from Frequency-Sliding Generalized Cross-Correlations Using Convolutional Neural Networks
Luca Comanducci, Maximo Cobos, Fabio Antonacci +1
The interest in deep learning methods for solving traditional signal processing tasks has been steadily growing in the last years. Time delay estimation (TDE) in adverse scenarios…
Frequency-Sliding Generalized Cross-Correlation: A Sub-band Time Delay Estimation Approach
Maximo Cobos, Fabio Antonacci, Luca Comanducci +1
The generalized cross correlation (GCC) is regarded as the most popular approach for estimating the time difference of arrival (TDOA) between the signals received at two sensors. T…
