用Matlab实现Huffman编码，解决对文本的压缩解压(Huffman coding with Matlab realize and solve the text compression decompression)

This document covers various aspects the Heston model. The structure and topics covered is as follows: Chapter 1 introduces the model and provides theoretical and graphical motivation for its robustness and hence popularity. It also discusses pricing using the Partial Differential Equation and Equivalent Martingale Measure techniques Chapter 2 discusses how the different components of the model can be evaluated computationally and how this can be achieved with different methods. These methods are then compared to each other. Chapter 3 addresses the calibration problem. Different methods are presented as well as practical implementation, results thereof, and comparisons. All the MATLAB code required to implement the model is provided in the appendix

一个用Mathmatica编写的动画演示程序(with an animation prepared by the Mathmatica Demonstration Program)

给出比较少见的16PSK的仿真算法，包括高斯信道，瑞利信道及线性时不变信道。其中，在瑞利信道中，给出了均衡前均衡后比较结果，从中可以看出均衡的效果(is relatively rare in the estimation algorithm, including Gaussian Channel, Rayleigh channel and the linear time-invariant channel. Of these, the Rayleigh Channel, is a balanced balanced ago after the results of the comparison, from which one can see the effect of balance)

用于求解并绘制两个直扩信号的二维循环相关函数及对应二维图(two dimensional circle correlation of two direct sequence spread spectrum signals )

图像的平面微分平方和能够反映图像高频分 量的能量。用计算平面微分平方和的方法在空间域上计算相邻像素亮度差值的平方和，对应于在频率域上计算图像高频分量的能量和，此值越大，图像对焦越准确(Differential square image plane and the image can reflect the energy of high frequency. Computational method of Planar Differential squares calculated in the space domain to the square of the difference between the brightness of adjacent pixels and corresponds to the image in the frequency domain calculation of high frequency energy and, this value is larger, the more accurate the image focus)
