Singer循环的LDPC码

LDPC codes from Singer cycles

L. Giuzzi, A. Sonnino

摘要:

编码理论的主要目标是设计有效的系统,以充分利用通信信道的容量,从而实现任意小的错误概率。低密度奇偶检验(LDPC)码是具有良好纠错能力的分组码族,其特征在于允许稀疏的奇偶检验矩阵。本文研究了有限射影空间的子空间在Singer圈作用下的轨道。

英文摘要:

The main goal of coding theory is to devise efficient systems to exploit the full capacity of a communication channel, thus achieving an arbitrarily small error probability. Low Density Parity Check (LDPC) codes are a family of block codes--characterised by admitting a sparse parity check matrix--with good correction capabilities. In the present paper the orbits of subspaces of a finite projective space under the action of a Singer cycle are investigated.
