LDPC coding for information bits with an information length K=N×r is performed on the basis of an extended parity check matrix having rows and columns extended by a predetermined puncture length L with respect to a parity check matrix of an LDPC code with a code length N of 69120 bits and a coding rate r of 14/16, so that an extended LDPC code having parity bits with a parity length M=N+L−K is generated. A head of the information bits of the extended LDPC code is punctured by L, so that a punctured LDPC code with the code length N of 69120 bits and the coding rate r is generated. The extended parity check matrix includes an A matrix of M1 rows and K columns expressed by a predetermined value M1 and the information length K=N×r, a B matrix of M1 rows and M1 columns, a Z matrix of M1 rows and N+L−K−M1 columns, a C matrix of N+L−K−M1 rows and K+M1 columns, and a D matrix of N+L−K−M1 rows and N+L−K−M1 columns. The present technology can be applied to data transmission and the like using an LDPC code."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmission device, transmission method, reception device, and reception method","description":"The present technology relates to a transmission device, a transmission method, a reception device, and a reception method for securing good communication quality in data transmission using an LDPC co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11463103","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.
