Thus, synchronization is accurately corrected and channel estimation is achieved using the reference signal included in the preamble symbol, thereby reducing a ratio of a pilot included in a data symbol."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmitting apparatus, receiving apparatus, and controlling method thereof","description":"A transmitting apparatus includes a symbol generator configured to generate a preamble symbol including signaling data and a reference signal, a frequency allocator configured to allocate first subcar","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813207","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.
