摘要 提出了一种Turbo级联码的编码结构,用同样度分配的非规则LDPC码作为分量码,以Tur-bo码的编码方式构成了一种Turbo LDPC码。在译码端,采用内外分别迭代的译码算法。仿真结果显示,在低信噪比情况下,Turbo LDPC码优于同长度的PCGC码、非规则的LDPC码和Turbo码。 A kind of Turbo concatenated code is presented which uses two same degree distribution pairs of irregular LDPC codes as the two component codes in Turbo structure. Simulation results show that at low SNR , the new Turbo concatenated code is superior to PCGC code, irregular LDPC code and Turbo code in performance.
