电力线噪声模型仿真

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)

基于杨氏干涉的位相物体测量系统及其相位测量算法的Matlab 程序实现(Based on Young' s interference phase measurement system objects and phase measurement algorithm Matlab program)

All five matlab file relate to the cluster structure of wireless sensor network. LEACH, BCDCP, ERP, HEED and so on are very helpful to do the simulation.

emd算法 还是比较详细准确的算法 英文注释(emd algorithm is more detailed and accurate algorithm for English Notes)

可以很好地解决机器人的最短路径规划问题，此代码用于解决四数码问题，可以通过修改初始化代码来设置起始点(Can solve the shortest path planning of the robot, this code is used to solve the four digital issues, you can set the starting point by modifying the initialization code)

说明：  给仿真信号加入噪声信号，比如白噪声、有色噪声等等(Added to the simulated signal noise signal, such as white noise, colored noise, etc.)

this is an example on how to implement an algorythm in matlab. This example use GUI Matlab. It use the grayscale and negation algorythm as algorythm s example.

说明：  应用在认知无线电频谱检测中。环境：经过加性白噪声的信号。功能：求解虚警概率和漏检概率。(Used in cognitive radio spectrum detection.Environment: after additive white noise signal.Function: to solve the false alarm probability and missed detection probability.)

锁频环又称为自动频率控制（AFC）环，其利用反馈回路对输入频率变化进行调整，最后达到对频率的跟踪，广泛应用于雷达，卫星导航等领域对多普勒频率的跟踪。(Locked loop, also known as automatic frequency control (AFC) loop, the use of feedback loop to adjust the input frequency changes, and finally achieve frequency tracking is widely used in radar, satellite navigation and other fields on the Doppler frequency tracking.)

语音信号端点检测的多种算法，其中包括了时域的短时能量算法，短时过零率算法，以及小波去噪的若干程序！(Endpoint detection of speech signals)
