Modeled reference signal parameters are generated using the digital DLOS IF signal and known locations of one or more receiving antennas, the transmitter, and the SP. A reference signal is generated based on the modeled reference signal parameters and feedback of a previously estimated Δϕ. The reference signal is correlated with the digital reflected IF signal to produce in-phase (I) and quadrature-phase (Q) correlation results. An estimated C/N0 and an estimated Δϕ for the digital reflected IF signal are calculated from the correlation results."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive hybrid tracking algorithms for radio signal parameters estimations","description":"A digital direct line-of-sight (DLOS) intermediate frequency (IF) signal of a DLOS component of an RF carrier signal transmitted by a transmitter located above the surface of the earth and a digital r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12007472","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.
