ID3
实现ID3算法,在结果中以树表示出来。决策树是对数据进行分类,以此达到预测的目的。该决策树方法先根据训练集数据形成决策树,如果该树不能对所有对象给出正确的分类,那么选择一些例外加入到训练集数据中,重复该过程一直到形成正确的决策集。(ID3 algorithm to achieve, in the results that come out to the tree. Decision tree is to classify the data, thus achieving the purpose of prediction. The decision tree training set of data according to the formation of the first decision tree, if the tree can not give the correct classification of all objects, then select a number of exceptions to the training set data, repeat the process until the correct decision set.)

The_Effects_of_Soft_Limitation_1996
软限幅效应,量化阶数及取样间隔对直扩数字匹配滤性能的影响 郭南1996
本文以典型的AID变换量化器和改进型抖动噪声量化器为倒t研究几个数字化参数对
直接序列扩频(DS/SS)数字匹配滤渡/相关性能(系统的处理增益和误比特率)的影响,给出理论分
析及计算机模拟结果 用最优化方法研究最佳软限幅问题;指出增加量化比特数与引入抖动噪声
相比能更有救地改善系统性能,而且只要采用三比特的量化就能使系统性能接近无穷量他的效
果.文中还讨论了取洋间隔以及噪声的归一化带宽对系统性能的影响。本文的结果可为台理设计
