代码说明:

  qc-ldpc码编程,围长为6,列重为3,无4环(The algorithm divides rows into three equal groups. The rows are then connnected to form a distance graph which is then transformed in to a matrix. Girth of six is maintained by avoiding four-cycles. No two rows are connected more than once (the row-column constraint).)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!
