Detecting Malicious Pilot Contamination in Multiuser Massive MIMO Using Decision Trees
Pedro Ivo da Cruz, Dimitri Silva, Tito Spadini +2
Massive multiple-input multiple-output (MMIMO) is essential to modern wireless communication systems, like 5G and 6G, but it is vulnerable to active eavesdropping attacks. One type…
Intelligent Fault Diagnosis of Type and Severity in Low-Frequency, Low Bit-Depth Signals
Tito Spadini, Kenji Nose-Filho, Ricardo Suyama
This study focuses on Intelligent Fault Diagnosis (IFD) in rotating machinery utilizing a single microphone and a data-driven methodology, effectively diagnosing 42 classes of faul…
Microphone Array Based Surveillance Audio Classification
Dimitri Leandro de Oliveira Silva, Tito Spadini, Ricardo Suyama
The work assessed seven classical classifiers and two beamforming algorithms for detecting surveillance sound events. The tests included the use of AWGN with -10 dB to 30 dB SNR. D…
Comparative Study between Adversarial Networks and Classical Techniques for Speech Enhancement
Tito Spadini, Ricardo Suyama
Speech enhancement is a crucial task for several applications. Among the most explored techniques are the Wiener filter and the LogMMSE, but approaches exploring deep learning adap…
Sound Event Recognition in a Smart City Surveillance Context
Tito Spadini, Dimitri Leandro de Oliveira Silva, Ricardo Suyama
Due to the growing demand for improving surveillance capabilities in smart cities, systems need to be developed to provide better monitoring capabilities to competent authorities,…
