It also comprises a step of selecting a synchronization position and the determination step comprises the estimation of a phase shift between computed partial correlations at the selected synchronization position."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for estimating a carrier-frequency shift in a telecommunication signals receiver, notably a mobile device","description":"This method for estimating a carrier-frequency offset in a telecommunication signals receiver comprises the following steps: computation of the partial correlations relating to several successive port","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8503504","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.
