Code construction for irregular shortened LDPC codes with good performance

摘要

A method for interlacing columns of different weights is proposed for a parity-check matrix H that results in good performing LDPC codes shortened or un-shortened. matrix H comprises a section H1 and a section H2, and wherein H1 has a plurality of different column weights and comprises a plurality of sub-matrices where columns of at least one weight are substantially interlaced between the sub-matrices.
