parity-check code

An improved decoding algorithm for low-density parity-check code ( LDPC) on finite-state Markov channels was presented and the corresponding factor graph representation was given.

针对有限状态Markov信道，提出一种改进的低密度奇偶校验码（low-Density Parity-check，LDPC）译码算法，并给出其因子图表示。

In the last decade, because of its innate parallel decode algorithm and excellent error correction performance, Low-Density Parity-Check code ( LDPC code) have been received close attention from numerous of investigator at home and broad.

低密度奇偶校验码（LDPC码）以其自然并行的译码算法和优异的纠错性能，近十几年来受到海内外众多研究学者的极大关注。
