An average power calculation unit calculates an average power for each of the differential signals. An optimal condition search unit determines the values of delay, phase and amplitude that result in the minimum average power, and sets the values in an optimal interference signal adjustment unit. The optimal interference signal adjustment unit adjusts the signal received by the sub antenna using optimal values for delay, phase and amplitude to obtain an optimal adjustment signal. A cancellation unit subtracts the optimal adjustment signal from the signal received by the main antenna to remove interference signals, and outputs a desired signal to a host device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Noise canceller device","description":"In a noise canceller device, interference signal adjustment units adjust delay, phase and amplitude of a signal received by a sub antenna under different conditions to obtain adjustment signals, and s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469110","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.
