本文提出了几种新的低密度奇偶校验（LDPC）码和系统重复累积（RA）码的构造技术。基于特定类别的组合设计，改进的代码设计的重点是高速率的结构码与恒定的列重量3和更高。所提出的代码是有效的编码，并表现出良好的结构特性。实验结果表明，该码在磁记录、光通信等高速信道中具有很好的应用前景。
This paper presents several new construction techniques for low-density parity-check (LDPC) and systematic repeat-accumulate (RA) codes. Based on specific classes of combinatorial designs, the improved code design focuses on high-rate structured codes with constant column weights 3 and higher. The proposed codes are efficiently encodable and exhibit good structural properties. Experimental results on decoding performance with the sum-product algorithm show that the novel codes offer substantial practical application potential, for instance, in high-speed applications in magnetic recording and optical communications channels.
