A specific implementation method includes: receiving, by a sending apparatus, N channels of bit signals, and performing serial-to-parallel conversion on any channel of bit signal of the N channels of bit signals, to generate two channels of first bit signals; performing delay control on the two channels of first bit signals, to generate two channels of code bit signals; performing QAM mapping on the two channels of code bit signals and other N−1 channels of bit signals, to generate a channel of quadrature electrical signal and a channel of in-phase electrical signal; modulating the quadrature electrical signal and the in-phase electrical signal, to obtain a transmit signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Code modulation and demodulation methods, apparatuses, and system","description":"The present invention relates to the field of signal processing, and discloses code modulation and demodulation methods, apparatuses, and a system, so as to reduce an envelope fluctuation degree of a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9762427","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.
