| 摘 要： | 提出了利用分解二进制序列构造的非正则低密度校验码的新颖简单的方法.仿真结果表明这种方法构造的低密度校验码在高斯白噪声信道BPSK调制下的迭代译码性能很好,并且在没有环长度为4的情况下具有较好的码重分布特性.

| Abstract: | A new and simple approach to construct irregular low-density parity-check(LDPC)code based on the binary sequence splitting was proposed.Experimental results show that constructed irregular LDPC code with iterative decoding perform well over the AWGN channel and have a good code weight distribution with 4-cycle free. |

| Keywords: | LDPC code Tanner graph cycle-free girth sequence splitting |
