Our result shows poor spectrum utilization in TV band and good potential for Cognitive radio.The idea of this paper is to detect the presence of primary users to avoid interference with secondary users in cognitive radio networks. The performance of Cognitive Radio (CR) systems with Energy ...
PURPOSE: To increase the number of users without increasing a spread band or reducing data transmission speed by performing spread spectrum modulation to transmission data signals, performing sampling, then extracting the signals of a prescribed band width and generating transmission signals. CONSTITUTION:...
Second, we jump to the other end of the query complexity spectrum and use extremely simple scene graphs as queries; this shows that our model is flexi- ble enough to retrieve relevant images when presented with more open-ended and human-interpretable queries. In addition, we directly evaluate ...
Since we are working with multi-spectral images, our method will also include a data regularization routine for using information from other energy bands, based on the gradient’s correlation across the acquired energy spectrum. 3.1. Mathematical Formulation Let 𝑢∈𝑅𝑀×𝑁u∈RM×N, where...

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by variations in brain function and structure. This study introduces an innovative approach to predict ASD using electroencephalography (EEG) data targeted at specific brain regions. By employing a Densely Connected Grap...
Ireland's telecom regulatory authority is floating a proposal to license some of the ultra-high-frequency (UHF) spectrum to be freed up by the transition to digital television for a mobile TV service that would initially serve major urban areas. The proposal from the Commission for Communications...
