  Lossless source coding is a kind of symbol when converting source code can be restored without distortion from the code source symbols to the original source coding. This article first briefly describes the lossless coding technology development and application; and then focus on the Shannon coding, fee Connaught coding, Huffman coding and arithmetic coding of the four principles of coding and coding steps, and compared with the corresponding examples of their Average code length and information transmission speed; Finally, the Huffman coding Matlab software simulation process, and gives some of the source, and an example of application, the output results are analyzed, conclusions are drawn.

  Content as follows: no distortion source coding is a kind of when source symbols, can convert code without distortion from code returned to the original source of the source coding symbols. This paper firstly introduces the without distortion encoding technology development and application; Then discussed emphatically shannon coding, feanor coding, hoffmann coding and the arithmetic coding of four kinds of coding method, the principle and encoding steps are compared with the corresponding sample the average yards long and information transmission speed; Finally, using the Matlab software realize the coding hoffmann the simulation process, also gives part of the source program, and illustrates the application of output, analysed and corresponding conclusions.
