pfx格式或者p121格式文件的解析器， PfxTest文件 使用一个BASE64编码的P12文件字节数组，默认密码123456，CERT为三级证书，使用BC库作为JCE实现(pfx test java code , decrypt a p12 format file (such as .pfx,.p12 file) the pfxtest use a sampled p12 file which is base64 encoded, the pfx password is 123456, and is an three level cert chain, the resolve use the BC lib ——the JCE open implemention)

K最邻近密度估计技术是一种分类方法，不是聚类方法。 不是最优方法，实践中比较流行。 通俗但不一定易懂的规则是： 1.计算待分类数据和不同类中每一个数据的距离（欧氏或马氏）。 2.选出最小的前K数据个距离，这里用到选择排序法。 3.对比这前K个距离，找出K个数据中包含最多的是那个类的数据，即为待分类数据所在的类。(K nearest neighbor density estimation is a classification method, not a clustering method. It is not the best method, but it is popular in practice. Popular but not necessarily understandable rule is: 1. calculate the distance between the data to be classified and the data in each other (Euclidean or Markov). 2. select the minimum distance from the previous K data, where the choice sorting method is used. 3. compare the previous K distances to find out which K data contains the most data of that class, that is, the class to which the data to be classified is located.)

This codes describe a basic implementation of cognitive radio networks.Hope it is useful.

说明：  关于ARNOLD算法的内容,对了解ARNOLD有参考意义(guanyu arnold suanfa de neirong)

本科时做的一个实验，关于３个算法的比较，有matlab代码，有说明文本，还有一些素材图片。(three algorithms about image process,include some image used in the process and pdf introducing the process.)
