matlab环境实现播放卡农，利用音频处理工具(Matlab environment to achieve playback Canon)

用matlab设计FIR维纳滤波器 假设一个点目标在x，y平面上绕单位圆做圆周运动，由于外界干扰，其运动轨迹发生了偏移。其中，x方向的干扰为均值为0，方差为0.05的高斯噪声；y方向干扰为均值为0，方差为0.06的高斯噪声。用该滤波器处理观测信号，得到其最佳估计。(FIR Wiener filter design using matlab Suppose a point target in the x, y plane around the unit circle in a circular motion due to external interference, its trajectory shift occurred. Which, x the direction of the interference of mean 0 and variance of 0.05 Gaussian noise y direction of the disturbance is zero mean Gaussian noise variance 0.06. Observed with the filter processing signal, to get the best estimate.)

在Matlab环境中，使用高阶有限差分算法实现双相介质地震波场正演模拟(Forward modeling for two-phase media)

说明：  几种前向神经网络的应用实例，用matlab编的源代码(Several prior to the application of neural network, using matlab made the source code)

只使用待测用户的观测数据，不需要其他用户（干扰用户）信息就可以抵消多址干扰进行检测的自适应检测器称为盲自适应多用户检测器，常简称为盲多用户检测。用LMS算法更新检测器系数时即为盲自适应多用户检测的LMS算法(Use only tested the user' s observations, no other user (interference user) information to be offset by multiple access interference detection and adaptive detector known as the blind adaptive multiuser detector, usually referred to as the blind multiuser detection. Detector with LMS coefficient update algorithm when it is blind LMS adaptive multiuser detection algorithm)

聚类树的matlab软件包。层次聚类分析器。(ClusTree is a GUI Matlab tool that: Enables an easy and intuitive way to cluster, analyze and compare some hierarchical clustering methods Consists of a two-step wizard that wraps some basic Matlab clustering methods and introduces the Top-Down Quantum Clustering algorithm. Provides a flexible and customizable interface for clustering data with high dimensionality. Allows both textual and graphical display for the clustering results. Can either apply hierarchical clustering to a dataset or analyze ‘pre-clustered’ results. )

The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block. The motor drives a mechanical load characterized by inertia J, friction coeficient B, and load torque TL . The speed control loop uses a proportional-integral controller to produce the quadrature-axis current reference iq* which controls the motor torque. The motor flux is controlled by the direct-axis current reference id*. Block DQ-ABC is used to convert id* and iq* into current references ia*, ib*, and ic* for the current regulator. Current and Voltage Measurement blocks provide signals for visualization purpose. Motor current, speed, and torque signals are available at the output of the Asynchronous Machine block.
