The method includes inserting one or more pilot time domain symbols between orthogonal frequency division multiplexing (OFDM) time domain symbols in the PL field to obtain a physical layer frame, and sending the physical layer frame to a receive end, where the preamble and the pilot time domain symbol are used together by the receive end to perform channel estimation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal sending method and apparatus","description":"A signal sending method and apparatus to improve channel estimation accuracy of a receive end to improve data decoding accuracy of the receive end, where the method is applied to a system whose physic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10505764","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.
