Description: This is a little console mode utility program which is able to
(de-)compress single files with a static Arithmetic compression
algorithm. You could easily add the RLE/BWT/MFT data
transformation algorithms. Just rip the corresponding classes
out of my HuffComp source code. I won t add these ones in the
next time. Platform: |

Description: 头压缩算法是一种常用的稀疏数组压缩算法，在数据联机分析处理（OLAP）等领域有着重要
应用。针对头压缩算法的特点，给出基于STL 的实现方法，并对解压算法进行改进。仿真实验表明，改进
后的解压算法的计算效率要优于原有解压算法-Head-compress algorithm was a commonly used algorithm for compressing sparse array, which was widely applied
in OLAP(Online Analytic Processing). According to the speciality of the head-compress algorithms, the implementation
based on STL(Standard Template Library) was presented, which improved on the decompressing process. The stimulation
results showed that the improved algorithm was more efficient. Platform: |

Description: 现代通信系统书籍仿真程序，不错的程序
供初学习者使用-The Slepian-Wolf (SW) cooperation proposed in [1] is probably the first practical cooperative
scheme that implements the idea of compress-and-forward. Through the exploitation of efficient
distributed source coding (DSC) technology, the authors of [1] demonstrate the effectiveness of
Slepian-Wolf cooperation in combating inter-user channel outage in wireless environment. In this
paper, we discuss the general framework of Slepian-Wolf cooperation using the two most popular
DSC technologies: the binning/syndrome approach and the parity approach. We show that the
latter is particularly useful in SW cooperation, since it is conceptually simpler, provides certain
performance advantages, and enables any (system) linear channel code to be readily exploited.
Examples using convolutional codes, low-density generator-matrix codes and low-density paritycheck
codes are demonstrated and practical algorithms for estimating the source-relay correlation
and for decoding the compound packets Platform: |

Description: The discrete cosine transform (DCT) is a technique for converting a signal into elementary
frequency components. It is widely used in image compression. Here we develop some simple
functions to compute the DCT and to compress images.
These functions illustrate the power of Mathematica in the prototyping of image processing
algorithms.

Description: Companding is essentially a technique for achieving non-uniform quantization. There are basically 2 methods which are most popular in literature.:-A-law companding and u-law companding. These algorithms help in achieving to an extend, compression. The given code shows how to compress a 14-bit code to 8-bit code and its digital implementation using matlab.
