小波算法去白噪声、高斯白噪声分析的源程序(Wavelet algorithm to white noise, Gaussian white noise analysis of the source)

并行和串行级联码已成为一种实用的方法，取得了良好的性能。在此论文中，我们将介绍并行和串行级联单奇偶校验乘积码。我们对这种码的码重分布进行了分析，其性能是有界的。仿真的结果确定了在高信噪比情况下的性能界限。这种码（与一些变种）的性能证明对于降低译码复杂性和适当的短码长具有相当良好的效果。(Parallel and serial concatenated code has become a practical way to obtain good performance. In this paper, we will introduce the parallel and serial concatenated single parity check product codes. We re-distribution of this code code analysis, and its performance is bounded. The results of the simulation to determine the performance limits in the case of a high signal-to-noise ratio. Proof of performance of this code (with some variants) having a fairly good effect for reducing the decoding complexity and the appropriate short code length.)

说明：  一种亚启发式(meta-heuristic)随机搜索算法，它从一个初始可行解出发，选择一系列的特定搜索方向（移动）作为试探，选择实现让特定的目标函数值变化最多的移动。(A meta-heuristic random search algorithm that starts with an initial feasible solution and selects a series of specific search directions (moves) as heuristics, selecting the moves that achieve the most changes in the value of a particular objective function.)

说明：  ：将信息论中熵的概念应用到特征选择中，定义了两种信息测度评价特征——误差熵和混叠熵，然后阐述了两种定义的不 用物理意义，分析了计算熵中最关键的区间划分问题，并提出一种较好的区间划分方法。(: The concept of entropy in information theory applied to feature selection, the definition of information measure evaluation of two features- error entropy and mixing entropy, and then describes the two definitions do not have the physical meaning of the calculation of entropy in the range of the most critical partitioning problem and propose a better method of interval division.)
