Repeating tree code repetition encoder for repeatedly outputting the information bits input to the code conversion of the present invention; Converting the code sequence repeats recursive and non-predetermined
This MATLAB function returns an m-by-n parity-check matrix, h, for a Hamming code of codeword length n = 2m–1.
Generate a parity-check matrix,h, for a Hamming code of codeword length 7. The function uses the default primitive polynomial in GF(8) to create the Hamming code. h = hammgen(3) h =3×71 0 0 1 0 1 1 0 1 0 1 1 1 0 0 0 1 0 1 1 1 ...
A q-ary LDPC code is a linear block code defined as the null space of a sparse parity-check matrix H over a finite field of q elements that is denoted by GF(q), where q is a power of a prime. From: OFDM for Optical Communications, 2010 ...

This MATLAB function returns parity-check matrix H for a quasi-cyclic LDPC code based on the input block size, blocksize, and the prototype matrix, P.
In this paper, we propose a design rule of rate-compatible punctured multi-edge type low-density parity-check (MET-LDPC) code ensembles with degree-one variable nodes for the information reconciliation (IR) of continuous-variable quantum key distribution
