LDPC Encoding Method Decoding Method Encoding device and Decoding Device for Structured LDPC

摘要

According to an embodiment of the present invention, there is provided an encoding method, a decoding method, an encoding device, and a decoding device for a structured LDPC, the encoding method comprising: determining a basic matrix of Mb × Nb used for encoding; An LDPC encoding operation is performed to obtain an Nbxz bit code word from the (Nb-Mb) xbit source data by the base matrix and the expansion factor corresponding thereto, where z is an expansion factor and 1 And is an integer greater than or equal to.
