The channelization code analyzer further includes a detector configured to detect from the plurality of despreaded signals a set of despreaded signals modulated with a predetermined first modulation scheme. A channelization code identification unit is configured to identify at least one active channelization code from the plurality of candidate channelization codes based on the detected set of despreaded signals. Further, a radio receiver apparatus, a second moment and fourth moment processing unit and a modulation scheme detector are described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection of active spreading codes and modulation schemes","description":"A channelization code analyzer for determining active channelization codes includes a despreading unit configured to despread a received signal with a plurality of candidate channelization codes to ge","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9794023","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.
