DEVICES AND METHODS FOR GENERATING A LOW DENSITY PARITY CHECK CODE FOR A INCREMENTAL REDUNDANCY HARQ COMMUNICATION APPARATUS

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 P 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.
