通过小波包分析计算柱塞流的特征值，奇异值(Through the wavelet packet analysis and calculation of the plunger flow characteristic value, singular value)

本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)

该M文件的编写将方波响应转化为脉冲响应的程序和将脉冲响应转化为方波。(The preparation of the M file into the square wave response procedures and the impulse response into a square wave pulse response.)

说明：  用遗传算法优化阵列，完成字典优化（减小列间相关度），实现更准确的DOA估计(With GA alg. this simulation file complete dictionary refine then getting better DOA estimate.)

PLL的simulink仿真模型，希望能有用，谢谢大家(PLL in simulink simulation models, hoping to be useful, thank you)

质心算法 基于MATLAB 毕设的源代码(Centroid algorithm is based on MATLAB)

I am simply extracting three types of features from the wavelet transform coefficients, these include: energy, variance and waveform length. You can modify and extract any types of features as you need. ** You need the wavelet toolbox to run this code.

几个UKF和EKF例子，本来在工具箱中附带，后经修改，以便易于理解和适应稍有不同的需求。(several UKF and EKF demos,which were attached with KF toolbox, and revised according to tracing purpose.)
