The root matrix includes three submatrices: an identity matrix in an upper-left-hand portion of the root matrix, an identity matrix in a lower-left-hand portion of the root matrix, and a circulant matrix in a right-hand portion of the root matrix. The circulant matrix equals the sum of an identity matrix and an identity matrix with rows shifted once to the right. Generating H includes expanding the root matrix by replacing 0 elements in the root matrix by a square matrix of 0 elements and replacing 1 elements in the root matrix by a shifted diagonal matrix. Non-zero elements of the diagonal matrix are selected from GF(q) based on the generator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of secure communication using low-density parity check coding","description":"A method of transmitting a message includes, for each data block, generating a root matrix using a generator, generating a quasi-cyclic matrix H using the root matrix, encoding the block using H to cr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11265012","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.
