基于等差矩阵的性质特征,提出了一种QC-LDPC(准循环低密度奇偶校验)码的新颖构造方法。该构造方法易于有效编译码,具有良好的围长特性,可有效避免四环,使生成的码字不受短环的干扰,且在硬件实现方面可节省存储空间。仿真结果表明:当误码率达到10-7时,该构造方法造出的高码率QC-LDPC(3780,3542)码与ITU-T G.975中的RS(255,239)码相比,其净编码增益提高了约2.1dB,具有更好的纠错性能;与QC-LDPC(4221,3956)码相比,净编码增益提高了0.35dB。

Simple Power Analysis Attack on the QC-LDPC McEliece Cryptosystem
It is known that a naive implementation of the decryption algorithm in the McEliece cryptosystem allows an attacker to recover the secret matrix P by measuring the power consumption.

Explicit construction of girth-eight QC-LDPC codes and its application in CRT method
For arbitrary code lengths of the form PL(P≥3L<sup>2</sup>/4+L-1),a new family of (4,L)-regular quasi-cyclic (QC) low-density parity-check (LDPC) codes was proposed explicitly with girth ight.Employing the new code as a component code in the ...

FPGA implementation of adaptive code rate QC-LDPC encoder [PDF]
准循环低密度奇偶校验码(QC-LDPC codes)相比其他的LDPC码具有简单的编码结构,拥有较好的应用前景。通过构造校验矩阵设计了不同码率和不同帧长的具有系统结构的QC-LDPC码,并分析了这些码的性能,随后将编码过程分阶段引入主从控制模块及复用基本SRAA组,设计了变码率和变帧长的编码器,并用Verilog HDL语言在Spartan 3 3s1500fg676芯片上实现了编码器的设计。综合报告表明:在使用适中的硬件资源情况下,系统最大频率达到了174.856 MHz,能满足高速编码的要求 ...
