压缩编码与解码程序，可以压缩字符型文件，且含有一个测试文件(Compression coding and decoding process)

卷积码的仿真及应用，通过matlab仿真过，得到了在不同信道上的性能(Convolutional code simulation and application, through the matlab simulation before, to get the performance in different channel)

calculates the Fresnel integrals using the error function for complex inputs abd calculates the field for each path of the Epstein & Peterson model

该函数用来计算任意函数的一阶偏导数(数值方法),小波包分析提取振动信号中的特征频率，可以提取一幅图中想要的目标。( This function is used to calculate the arbitrary function of th)

说明：  matlab簡介與入門使用MATLAB為各種動態系統模擬、數位訊號處理、科學計算、科學目視等領域的標準程式語言(Introduction and Getting Started with MATLAB matlab to use a variety of dynamic system simulation, digital signal processing, scientific computing, scientific standards for the areas of visual programming language)

说明：  空时码的编码程序，包含不同码字的比较和多天线设计(STBC source code with MIMO)
