A method and apparatus for encoding and decoding data is provided herein. During operation, A structured parity-check matrix H is provided to the encoder and decoder, where H is an m by n matrix and an expansion of a model matrix Hbm of size mb by nb, where m=mb×z and n=nb×z. For a given code rate, multiple code sizes are accommodated by allowing both the model matrix size nb and the expansion factor z to vary.
