摘要

证明了循环子群独立的两个判据。建立了基于独立子群的正则二进制LDPC码集合。对于所得到的编码结构，证明了不存在长度为4的循环的条件。给出了码字在加性高斯白噪声(AGWN)信道上传输时用Sum-Product迭代算法接收到的码结构的结果。

Low-density parity-check codes based on the independent subgroups

Two criteria of cyclic subgroups independence are proved. The ensemble of regular binary LDPC codes which are based on independent subgroups, is built. The condition of absence of the cycles of the length 4 is proved for the resulting code construction. The results of the received code constructions are presented for the iterative algorithm Sum-Product when the codeword is transmitted over channel with additive Gaussian white noise (AGWN).
