The interference canceller includes: an oversampling circuit oversampling an XPAN transmission signal originated from a transmitter of the network device and thereby generating an oversampled signal having a frequency higher than the frequency of the receiver's clock; a clock difference calculating circuit calculating a clock difference between the transmitter's clock and the receiver's clock; a sample rate converter processing the oversampled signal according to the clock difference and thereby generating a conversion signal having a frequency lower than the frequency of the oversampled signal and equal to the frequency of the receiver's clock; and a cancelling circuit generating the cancellation signal according to the conversion signal and determining coefficients of the cancelling circuit according to an error signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interference canceller and method for cancelling interference","description":"Disclosed is an interference canceller capable of generating a cancellation signal for reducing cross port alien near-end (XPAN) crosstalk of a reception signal received by a receiver of a network dev","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11239900","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.
