- Lempel–Ziv–Welch (LZW) is a universal lossless data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch. It was published by Welch in 1984 as an improved implementation of the LZ78 algorithm published by Lempel and Ziv in 1978

- The name of the project is “RUN LENGTH ENCOADING”. In this project transmit the data use different compression Techniques. In these Techniques input date is to be encoded. By use the techniques the input data is to be compress .In this project it is
DAIMA
- OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。-OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than
PCA
- PCA算法：通过将高维矩阵降维来压缩文件或是查询数据-PCA algorithm: by reducing the dimension of the high-dimensional matrix to compress the file or query data
leach
- LEACH is a hierarchical protocol in which most nodes transmit to cluster heads, and the cluster heads aggregate and compress the data and forward it to the base station(sink).
算术编码实验
- 算数编码，包括： 对文件符号进行概率统计，生成编码表； 对文件进行压缩编码； 对文件进行解压缩，比较原始数据和解压后的数据之间是否有损耗。(Arithmetic coding, including: The probability statistics of the file symbols are carried out and the coding table is generated. Compress and encode the file. The file is deco
practice
- 本程序使用LZW算法对图像进行压缩。压缩编码是一种先进的数据压缩技术，属于无损压缩编码。对于简单图像和平滑且噪声小的信号源具有较高的压缩比，并且有较高的压缩和解压缩速度。(This program uses the LZW algorithm to compress the image. Compression coding is an advanced data compression technology. It belongs to lossless compression coding.
lzw_encode
- lzw建立字典，可以对文本数据进行压缩。(LZW a dictionary, can compress text data.)
Lossless image compression using Matlab
- it is basic step to compress image which is lossless.. what lossless mean ? image which can be reproduce completely after compression.. check it out the code and the data set
