The LDPC code includes information bits and parity bits, and a parity check matrix H is composed of an information matrix portion corresponding to the information bits of the LDPC code, and a parity matrix portion corresponding to the parity bits. The information matrix portion of the parity check matrix H is represented by a parity check matrix initial value table that shows positions of elements of 1 in the information matrix portion in units of 360 columns. The present technology may be applied to LDPC encoding and LDPC decoding."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data processing apparatus and data processing method","description":"The present technology relates to a data processing apparatus and a data processing method which enable provision of an LDPC code that achieves good error-rate performance.An LDPC encoding unit perfor","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10530389","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.
