| 摘 要： | LDPC码由于其卓越的纠错性能引起了学术界的广泛重视，当前LDPC所面临的一个主要问题是其编码复杂性的问题。本文给出了一种半代数半随机的非正则LDPC码构造方法，由该方法所构造的校验矩阵具有近似下三角特性，从而可以大大降低LDPC的编译码复杂性，同时具有与完全随机LDPC码相匹配的性能。

| Abstract: | LDPC code with excellent error-correcting performance has draw extensive interests in the academic circles. The main problem that LDPC is facing is its encoding paper proposes one irregular low-density parity-check code, called one complexity. This half-algebra and half-random code. Parity check matrix of this code is not only close to triangle, but also reduces greatly the encoding complexity. This code also has the same excellent performance as random LDPC. |
