网规网优之用，用于绘制基站扇区图，地理化显示基站方便工程师进行查看。(Net regulatory network optimization purposes, used to map the base station sector maps, geographic-based display base stations to facilitate engineers to view it.)

Jepg2000的压缩解压(Jepg2000 compression decompression)

压缩感知的经典书籍，请大家下载查阅，好的东西大家一起分享哦，谢谢大家了！！(compresed sensoring)

有关算术编码对文本压缩的程序在c++环境中实现(about arithmetic compressed)

这是一个基于LZARI算法的数据压缩的类.Haruhiko Okumura 于1989年7月4日用C语言写实现了这个算法.但是上面用到了一些全局或静态的变量,在MFC下用起来很不方便.作者把它改写成了一个C++类,使它可以方便的压缩和解压缩。(LZARI algorithm based on the type of data compression. Haruhiko SAP in 1989, July 4 C language daily wrote realization of this algorithm. But above uses some static or global variables, using the MFC which are very convenient. Authors rewrite it became a category C, it can be to facilitate the compression.)

一个压缩软件的SDK，有例子！ 请大家尝试！(a packer software sdk)

赫夫曼编/译码器源码，已生成的每个字符的赫夫曼编码，对任意字符文本进行编码，再译码(Huffman encoder/decoder source code, Huffman coding, each character has been generated, the text of any character encoding, decoding)

这是一个自己写的关于fft变换的快速源程序，可以达到很高的性能。(This is an fft transform himself wrote about the rapid source, you can achieve high performance.)

说明：  vc 典型模块 是一个图像压缩显示的程序(vc typical module is shown in an image compression program)

哈夫曼编码译码系统，设置发送者和接受者两个功能， 发送者的功能包括： ①输入待传送的字符信息； ②统计字符信息中出现的字符种类数和各字符出现的次数（频率）； ②根据字符的种类数和各自出现的次数建立哈夫曼树； ③利用以上哈夫曼树求出各字符的哈夫曼编码； ④将字符信息转换成对应的编码信息进行传送。 接受者的功能包括： ①接收发送者传送来的编码信息； ②利用上述哈夫曼树对编码信息进行翻译，即将编码信息还原成发送前的字符信息。 (Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)
