A Method and Apparatus for Construction and Encoding of Low Density Parity Check Code

摘要

The present invention relates to a design and encoding method and a device for a low-density parity check code. The design and encoding method for a low-density parity check code according to one embodiment of the present invention may include the steps of: (a) generating a proto-matrix for a PBRL (Protograph-Based Raptor-Like) LDPC (Low-Density Parity-Check) code; (b) adding at least one edge to the proto-matrix; and (c) performing encoding using the proto-matrix to which the at least one edge is added to generate a codeword.
