1. A method of encoding data using an LDPC code, which is defined by an (n-k)×n parity check matrix H, the method comprising: encoding source data using the parity check matrix H to output codeword, the parity check matrix H including Hand Hto meet H=[H| H], where Hhas ...
Techniques to support low density parity check (LDPC) encoding and decoding are described. An apparatus includes at least one processor and a memory coupled to the at least one proc

This example shows how to use the pyAerial Python bindings to run 5G NR LDPC encoding, rate matching and decoding. Information bits, i.e. a transport block, get segmented into code blocks, LDPC encoded and rate matched onto the available time-frequency resources (resource elements), all ...
因此,系统中的QC-LDPC译码采用了归一化的最小和译码算法(Normalized Min-Sum Decoding Algorithm)[8],该算法在横向迭代过程中,采用近似算法,将横向迭代简化为数值比较过程,即将非线性关系变换为线性关系,从而减小了译码复杂度,同时通过调整比例系数,在非线性关系变换为线性关系的过程中增加BP算法和MSA两种算法间的运算...
