由切比雪夫权值矢量及阵元间距画波束方向图：有x输入，计算该方向的值,否则计算所有方向的值，画出方向图(By the weight vector and the array element spacing beam pattern draw: there is x input, calculate the value of the direction, otherwise the value calculated in all directions, draw the direction of graph)

共轭正交镜像滤波器组的设计。令N=22,wp=0.45pi,用切比雪夫最佳一致逼近法设计单带滤波器G(z),在得到半带滤波器Hlf(z). (conjugate mirror filters orthogonal design. Order N = 22, wp = 0.45pi. Chebyshev with the best approximation consistent single-band filter design G (z), with the half-band filter Hlf (z).)

视频监控，如果有东西经过监控区域就语音报警（有贼闯入）利用帧之间做差的方法(Video surveillance, if there are things after monitoring the regional voice alarm (the thief broke into) the use of the frame do the difference between method)

bartlett 波束形成，可实现matlab仿真分析 程序包括注解等必要说明(bartlett beamforming)

说明：  遗传算法，分为个7个子函数：分别为编码、解码、选择、交叉、变异、目标函数和总调用。有详细的注释。(Genetic algorithm, into a seven sub-functions: respectively, encoding, decoding, selection, crossover and mutation, the objective function and the total calls. There are detailed notes.)

一种基于easy代码，利用小波进行周跳探测的技术，内附实例。(Based on easy code, cycle slip detection using wavelet technology, enclosing instance.)

1,、设置变量和参量： 　　X(n)为输入向量，或称为训练样本 　　W(n)为权值向量 　　e(n)为偏差 　　d(n)为期望输出 　　y(n)为实际输出 　　η为学习速率 　　n为迭代次数 　　2、初始化，赋给w(0)各一个较小的随机非零值，令n=0 　　3、对于一组输入样本x(n)和对应的期望输出d，计算 　　e(n)=d(n)-X^T(n)W(n) 　　W(n+1)=W(n)+ηX(n)e(n) 　　4、判断是否满足条件，若满足算法结束，若否n增加1，转入第3步继续执行(, set the variables and parameters: X (n) is the input vector, otherwise known as the training sample W (n) for the weight vector e (n) for the deviation d (n) is the desired output y (n) is the actual output η is the learning rate n is the number of iterations)
