The radio receiver receives, from the radio transmission system, an OFDM data signal modulated on a set of OFDM subcarriers within the tuned channel. The channel filter has a passband that is wider than the channel bandwidth of the tuned channel such that the filter passes i) said OFDM data signal, ii) an in-channel reference signal, and iii) an out-of-channel reference signal. The radio receiver comprises channel estimation logic configured to use both reference signals to calculate a channel estimate for an OFDM subcarrier within the tuned channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"OFDM channel estimation","description":"A radio receiver of a radio communication system is configured to tune to a radio channel by generating a periodic signal, mixing the periodic signal with radio signals received from a radio transmiss","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11477052","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.
