A vectoring control entity then determines crosstalk channel coefficients from the other line into an inband spectrum and an out-of-band spectrum of the line, and performs precoding processing on a to-be-sent data signal of the line to eliminate impact of crosstalk from the other line to the inband and out-of-band spectrums of the line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Crosstalk estimation method, apparatus, and system","description":"A crosstalk processing method, an apparatus, and a system comprise a transceiver of a line that generates, respectively according to pilot sequences allocated by a vectoring control entity, pilot trai","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9756178","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.
