Abstract
The present disclosure relates to a method, system, and non-transitory computer-readable storage medium for constructing a base matrix of a PBRL LDPC code, comprising: determining at least one candidate sub-matrix of a PBRL LDPC code based on a base matrix of a QR-QC-LDPC code; obtaining at least one count of cycles with at least one preset length for each of the at least one candidate sub-matrix; and determining a first sub-matrix of the base matrix of the PBRL LDPC code based on the at least one count of cycles.

A method for constructing a base matrix of a Protograph-based Raptor-like (PBRL) LDPC code, comprising:
- determining at least one candidate sub-matrix of a PBRL LDPC code;
- obtaining at least one count of cycles of at least one preset length for each of the at least one candidate base matrix;
- determining a first sub-matrix of the base matrix of the PBRL LDPC code based on the at least one count of cycles;
- and
- obtaining an optimized first sub-matrix by masking the first sub-matrix based on degree distributions of the PBRL LDPC code, wherein the degree distributions are determined by a Differential Evolution algorithm.
(canceled)
A system for constructing a base matrix of a Protograph-based Raptor-like (PBRL) LDPC code, comprising:
- at least one non-transitory storage medium including a set of instructions;
