Script for computing BER with Binary Convolutional Code and Viterbi decoding with finite survivor state memory Convolutional code of Rate-1/2, Generator polynomial - [7,5] octal Hard decision and soft decison decoding is used.

利用最速下降法计算最小曲面的面积，初始条件为0，边界条件为正方形固定边界。(Using steepest descent method to calculate the minimum surface area. Initial condition is 0, while boundary condition is square fixed values.)

绘制误码率与信噪比关系曲线，可以把gmsk、msk等一些调制解调技术的误码率和信噪比的关系曲线画出来(Plotting the error rate curve)

说明：  通过使用cdif的算法，实现对于不同信号的分选工作。(Through the use of CDIF algorithm, to achieve the separation of different signals.)

digital communication codes

说明：  对一列数据波形进行画图，频谱、功率谱分析。参数根据需要改动一下即可(Waveform data of a drawing, spectrum, power spectrum analysis. Click to change parameters as needed)

说明：  标准遗传算法求解TSP。算法采用交叉、变异、赌转轮选择(Genetic Algorithm for TSP)

Toolbox in Matlab for pattern recognition

该程序代码用于求解超越方程，绘制频散曲线，自行可以更改基本参数或方程形式加以利用(Solve the transcendental equation, draw the dispersion curve)

原始数据存储为excell文件，先将数据进行预处理，再通过SVM进行模型的建立与预测。(The data are stored as a excell file, preprocessing the original data and builting the SVM model.)
