Title:
INFORMATION PROCESSING METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/201540
Kind Code:
A1
Abstract:
An encoding method, an apparatus, a communication device and a communication system. The method comprises: using a low-density parity-check (LDPC) matrix to encode an input bit sequence, a base graph of the LDPC matrix being expressed as a matrix of m rows and n columns, m being an integer greater than or equal to 5, n being an integer greater than or equal to 27, the base graph at least comprising a sub-matrix A and a sub-matrix B, the sub-matrix A being a matrix of 5 rows and 22 columns, the sub-matrix B being a matrix of 5 rows and 5 columns, the sub-matrix B comprising a column having a weight of 3 and a sub-matrix B' having a dual-diagonal structure. The encoding method, the apparatus, the communication device and the communication system support encoding requirements for information bit sequences of various lengths.
