This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.

SimulationOfCommunicationSystems(2NdEd)
系统深入得多，一些在第一本中只略微论及的高级内容，这里讲得完整透彻。理论与实践并重，可操作性强。例题都有可直接运行的matlab文件，正文中也给出了关键部份方便阅读。读完这本书，住真水平可以上一个台阶，基本上可以达到系统级仿真的能力。(System is much more depth, some in the first book deals with only a slight premium content here put a complete and thorough. Theoretical and a practical, easy to operate. Example are directly run matlab file, the text also gives a key part of user-friendly. After reading this book, the level of living can be really a new level, but basically can achieve system-level simulation capabilities.)
