文件中包括的随机数发生器，将 Alist 矩阵转换成一般矩阵，做的 enc 部分。此 enc 方法只侧重于下三角矩阵，它可以变得更容易得到 enc 消息。希望此文件可以帮助您很多有关如何进行编码与低三角奇偶校验矩阵的 LDPC 码。我也写一个 matlab 文件来检测代码 c 是正确还是不。

The dynamics of orbit uncertainty in an unstable orbital environment are discussed with specific application to the orbit determination of a halo orbit about the Earth{Sun L1 point. This article documents a simplified orbit determination covariance program developed under Telecommunications and Mission Operations Division Technology support. The program is ideally suited to investigate spacecraft trajectory navigation in challenging environments, where the basic dynamics of the trajectory can no longer be modeled using near-Keplerian motion.

引入PEG（Progressive-edge-growth）算法来构造适合线性时间编码的LDPC校验矩阵，译码时采用简化最小和Min-Sum译码算法实现简化译码．仿真结果表明，该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日，并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码．同时通过采用最小和Min-Sum算法降低译码复杂度．-The introduction of PEG (Progressive-edge-growth) algorithm to construct suitable for linear time encoding of LDPC check matrix, decoding simplified when the smallest and the Min-Sum decoding algorithm decoding simplified. Simulation results show that this method can construct LDPC codes suitable for linear time encoding on lower triangular calibration matrix, and constructed using this method the performance of LDPC code is very close to the original PEG algorithm constructed LDPC codes. At the same time through the use of the smallest and the Min-Sum decoding algorithm to reduce complexity.
