The program simulates convolutional code using soft-decoding viterbi algorithm. The choice of generator matrix (G) determines the code rate (1/R) and constraint length of the code (K).

常见的几种绘图算法的matlab实现--数学模型的建立与求解多需要此算法(Several common drawing algorithm matlab realize- mathematical modeling and solving more need for this algorithm)

Powell是一种非常稳健的非线性最优化算法（当然，整个求解过程中需要一些辅助的技巧，否则可能达不到“稳健”标准）。(Powell is very usefull )

实现基于NeuroScan平台采集的脑电信号的数据分类、打标等功能(Realize the functions of data classification and marking, etc.of EEG collected by NeuroScan platform)

脑电信号分析 ，脑电样本熵特征计算，样本熵程序(SmapleEn EEG analysis)

变步长自适应滤波算法，对VS—LMS算法进行了改进，建立了步长因子μ与误差信号e（n）之间另一种新的非线性函数关系．理论分析和计算机仿真结果表明，该关系不仅具有原有算法收敛速度快的优点，而且在低信噪比环境下比原有算法具有更好的抗噪声性能．(The variable step size adaptive filtering algorithm is discussed, and the VS-LMS algorithm is improved. A new nonlinear function relation between the step size factor μ and the error signal e (n) is established. Theoretical analysis and computer simulation results show that the proposed algorithm not only has the advantages of high convergence speed of the original algorithm, but also has better anti- noise performance in the low SNR environment than the original algorithm.)
