The channel information generation apparatus performs spatial division multiplexing in an OFDM-based wireless communication system. The channel information generation apparatus includes a codebook storage unit for storing a predefined codebook, a channel correlation information unit that receives channel information corresponding to each of a plurality of sub-carriers and calculates channel correlation coefficient information between the sub-carriers based on the received channel information, and an index calculation unit that calculates an index of an optimal matrix of matrices stored in the codebook storage unit based on the channel information, the channel correlation coefficient information, and the codebook."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel information generating device and method for spatial division multiplexing algorithm in a wireless communication system, and data transmission apparatus and method adopting the same","description":"Provided are a channel information generation apparatus and a method for spatial division multiplexing in a wireless communication system and a data transmission apparatus and a method using generated","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8509052","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.
