The receiver uses a converter to make binary hard decisions performs n times oversampling, then obtains a symbol decision value, calculates a timing correlation value for each plurality of partition phases, and calculates a cumulative timing correlation value for a specific period or number of additions. The receiver determines whether its sampling frequency is higher or lower than a correct symbol rate, appropriately shifts a sampling position, and makes reception while maintaining the correct sampling position thereby enables data deviation caused by a frequency offset to be compensated on the fly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Compensation for data deviation caused by frequency offset using timing correlation value","description":"A method and circuitry for detecting a frequency offset (Δ) between data at a transmission symbol rate (fTx) transmitted from a transmitter and a reception sampling frequency (fRx) operating in a rece","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514987","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.
