Simulation-of-communicati

用来生成分形山的matlab程序，直接运行既是用中点法，迭代生成分形山，非常好用(Health ingredients to the matlab procedure Katayama, both directly run by the mid-point method, iterative Katayama Health ingredients, very easy to use)

小电流接地系统发生接地故障时，利用prony算法提取暂态特征分量并利用相关分析法实现选线取得很好的效果，有效的排除了干扰信号的影响，结论明显、准确性高。(When the small current grounding system occurs ground fault , we use prony algorithm to extract the transient characteristics of the component and line selection by using correlation analysis. The simulation present that the algorithm effectively eliminate the influence of interfering signal. The result has a good effect and high accuracy obviously.)

QPSK调制（自己调节一个关键参数就可以实现8PSK，16PSK，32PSK等实验图像）(QPSK modulation)

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. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.
