The coupler couples a portion of the transmitted signal to the variable reflector, whereupon the variable reflector generates the cancellation signal based on the operational parameter, for transmission to the combiner via the cancellation signal path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, system and apparatus for radio-frequency echo cancellation","description":"An RFID echo cancellation assembly includes: a circulator defining a transmission path from a transmit module to an antenna module, and a reception path from the antenna module to a receive module; a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10515240","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.
