A receiver includes a reception processing unit that separates received data into layer data, a decoding unit that generates a soft-decision value for each of the layers, a combining unit that combines soft-decision values corresponding to information data mapped to the plurality of layers in duplicate, and a deciding unit that performs hard-decision on the layer data using a soft-decision value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-antenna communication apparatus and method of multi-antenna communication","description":"A transmitter includes a mapping unit that maps first information data to a first layer and maps second information data a part of which is duplicative of and a part of which is different from the fir","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462870","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.
