Cyclostationary Statistical Models and Algorithms for Anomaly Detection Using Multi-Modal Dataeess.SP
A framework is proposed to detect anomalies in multi-modal data. A deep neural network-based object detector is employed to extract counts of objects and sub-events from the data. A cyclostationary model is proposed to model regular patterns of behavior in the count sequences. The anomaly detection problem is formulate…
Power load forecast with Machine Learning is a fairly mature application of artificial intelligence and it is indispensable in operation, control and planning. Data selection techniqies have been hardly used in this application. However, the use of such techniques could be beneficial provided the assumption that the da…
Additive asynchronous and cyclostationary impulsive noise limits communication performance in OFDM powerline communication (PLC) systems. Conventional OFDM receivers assume additive white Gaussian noise and hence experience degradation in communication performance in impulsive noise. Alternate designs assume a parametr…
Spectrum Sensing and Signal Identification with Deep Learning based on Spectral Correlation Functioneess.SP
CNN model for efficient wireless spectrum sensing and signal identification.
problem Efficient utilization of scarce wireless spectrum.
method Convolutional Neural Network (CNN) based on spectral correlation function.
result Significant performance gains over existing methods.
Internet-of-Things (IoT) devices that are limited in power and processing are susceptible to physical layer (PHY) spoofing (signal exploitation) attacks owing to their inability to implement a full-blown protocol stack for security. The overwhelming adoption of multicarrier techniques such as orthogonal frequency divis…
