An average power calculation unit obtains average power of the received signals. A normalization unit obtains a normalized correlation value obtained by normalizing the correlation value by the average power. The present technology can be applied to a case where a P1 signal being a preamble signal is detected from a received signal such as DVB-T2, for example."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Prevention of erroneous detection of signal","description":"The present technology relates to a reception device, reception method, and program that can prevent erroneous detection of a predetermined signal, such as a P1 signal, included in, for example, a rec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838735","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.
