The noise suppression device also includes: an asymmetric component detector that detects an asymmetric component in |X0(n)|; a suppressor that calculates a discrete Fourier series X1(n) by multiplying the value corresponding to the asymmetric frequency bin by a first factor and multiplying the other values by a second factor in X0(n); and an IDFT executor that performs inverse discrete Fourier transform on X1(n) to obtain a discrete-time signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Noise suppression device, noise suppression method, and reception device and reception method using same","description":"A noise suppression device includes: a DFT executor that expands a baseband signal into a discrete Fourier series X0(n), the baseband signal being generated by mixing an AM broadcast wave signal inclu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11296739","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.
