Additional tasks may include, for example, radio frequency (RF) fingerprinting on the extracted signal to identify an RF device that produced the extracted signal. Other classification and regression tasks may also be performed by the MTL neural network model."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-task learning neural network framework for RF spectrum sensing and classification","description":"A signal sensing and classification system, including: a detection module for obtaining a spectrum of signals; a separation module for extracting a signal from the spectrum of signals; and a multi-tas","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11997728","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
