Radio frequency (RF) spectrogram analysis for indoor human activity recognition has traditionally relied on supervised learning with larger labeled datasets. We present a novel framework that employs ...

Bengalese finch song analysis is essential in bioacoustics for studying avian communication. Spectrograms visually represent audio signals, displaying frequency content over time. When a finch sings, ...

Abstract: When modelling, analysing, and simulating mobile radio channels, it is generally assumed that the speed of the mobile station (MS) is constant. In practice, however, the mobile speed varies ...
