摘要
Devices and methods are disclosed for generating on the basis of a first protograph matrix P1 of size m×n, wherein the first protograph matrix P1 defines a first code H1, a second protograph matrix P2 of size (m+d)×(n+d), wherein the second protograph matrix P2 defines a second code H2. The device comprises a processor configured to: generate an auxiliary protograph matrix P′ of size (m+d1)×(n+d1) on the basis of the first protograph matrix P1 using row splitting; generate d2 random integer numbers, wherein d2=d−d1; generate a binary matrix M of size d2×(n−m), wherein rows of the binary matrix M are generated on the basis of the d2 random integer numbers; generate a matrix M′ by lifting the binary matrix M; Other operation steps are also included.
