理查森（Richardson）和Urbanke开发了一种强大的方法密度演化，该密度演变为各种渠道决定了不规则的低密度平价检查代码集合的能力。我们开发了一般的密度演化，以缩小代表合奏，并表明它包括常规表示作为一种特殊情况。此外，我们提供了一个在二进制擦除通道和二进制输入添加剂白色高斯噪声通道上使用的代码集合的示例，这些噪声与具有常规表示形式的高度优化的合奏具有更好的阈值。关键词：密度演化，不规则的低密度奇偶校验检查代码，低密度均等 - 检查代码，信念传播
Richardson and Urbanke developed a powerful method density evolution which determines, for various channels, the capacity of irregular low-density parity-check code ensembles. We develop generalized density evolution for minutely represented ensembles and show it includes conventional representation as a special case. Furthermore, we present an example of code ensembles used over binary erasure channel and binary input additive white Gaussian noise channel which have better thresholds than highly optimized ensembles with conventional representation. key words: density evolution, irregular low-density parity-check codes, low-density parity-check codes, belief propagation
