Hierarchical mixed frequency
Web12 de ago. de 2024 · In this paper, some challenging problems in signal detection and modulation classification have been discussed. We employed signal cyclostationary theory and Support Vector Machine (SVM) method to blindly detect and classify mixed signals, which have significant overlap in both time domain and frequency domain. Web30 de jan. de 2024 · Mixed cross-valence emotions (e.g., feeling both nervous and alert) are not central to this hierarchical scheme but are compatible with it. We examine the frequency of pure emotional states, same-valence emotional blends, and cross-valence mixed emotions in a large momentary mood sample.
