Latest Patents

Keke Liu holds a patent titled "Method of and apparatus for generating spatially-coupled low-density parity-check code." This patent describes a method, apparatus, and non-transitory computer-readable recording medium for generating an algebraic Spatially-Coupled Low-Density Parity-Check (SC LDPC) code. The method involves selecting an LDPC block code over a finite field GF(q) with a girth of at least 6. It includes constructing a parity-check matrix H from the selected LDPC block code, replicating H a user-definable number of times to form a two-dimensional array H, and constructing a masking matrix W with a user-definable spatially-coupled pattern. The process culminates in masking a sub-matrix of H using W to obtain a spatially-coupled parity-check matrix H, wherein a null space of H is the algebraic SC LDPC code.
