摘要

利用Sidon序列构造了一组周长至少为8的拟循环低密度校验码(LDPC)。这些代码可以使用简单的移位寄存器进行编码。此外，在短至中等长度的准循环码的误码率和分组误码率方面，这些准循环码的表现接近随机渐进边缘增长(PEG) LDPC码。

New quasi-cyclic LDPC codes with girth at least eight based on Sidon sequences

A new family of quasi-cyclic low-density parity-check (LDPC) codes of girth at least eight is explicitly constructed from Sidon sequences. These codes can be encoded using simple shift-registers. Furthermore, for short to moderate lengths these quasi-cyclic codes perform close to random progressive edge-growth (PEG) LDPC codes in terms of bit-error probability and block-error probability, collectively.
