The disclosure solves a problem in the related art that a CDMA synchronization method possesses a wrong sampling situation, which results in a high bit error rate of a receiving end, and reduces the bit error rate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for reducing bit error rate in CDMA communication system","description":"A method and a device for reducing a bit error rate in a Code Division Multiple Access (CDMA) communication system are described, wherein this method includes: a sample sequence Iin of an in-phase com","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9654254","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.
