MATLAB实现EMD分析振动信号时的波形匹配延拓，此方法可以一定程度上降低希尔伯特黄变换引起的端点效应(MATLAB to achieve EMD analysis of vibration signals when the waveform matching extension, this method can be reduced to some extent, the Hilbert yellow transform caused by the endpoint effect)

Laurent分解是一种对连续相位调制信号的在数学上的推到，能够严格重构CPM信号(Quotient is a value that is a value of a value that is a value of a value that is a value of a value that is a value of a value that is a value of a value that is a value of a value that is a value of a value that is a value of a that is a value that is a value for a that is a value that is a value for a value, U591F u4E25 u683C u91CD u6784CPM u4FE1 u53F7)

bmc music 对bpsk信号的doa估计(bmc music for bpsk)

说明：  用于菊萍时间序列的复制小波morlet小波再matlab上的程序，稍加修改分析文件名和年份即可(菊萍 wavelet time series for the program and then on the copy matlab wavelet morlet, slightly modified to analyze the file name and year)

• To design a GUI in MATLAB for Dual-Tone Multi-Frequency (DTMF) telephone key pad, including DTMF Signal generator and DTMF tone detector • To simulate the DTMF signals with noise based on the specifications given. • To decode and display the DTMF signals by using FFT algorithm

空间谱估计算法，是研究信号噪声比的。效果还可以(Spatial spectrum estimation algorithm, is to study the signal-noise ratio. Effects can also be)

说明：  刘金坤著的《先进PID控及其matlab仿真》一书中的例子的源代码。(刘金坤of the &quot Advanced PID control and its simulation matlab&quot one example of the book' s source code.)

simulink的仿真有两个阶段：一个为初始化，这个阶段主要是设置一些参数，像系统的输入输出个数、状态初值、采样时间等；第二个阶段就是运行阶段，这个 阶段里要进行计算输出、更新离散状态、计算连续状态等等，这个阶段需要反复运行，直至结束。(simulink simulation has two phases: one for initialization, this stage is mainly to set some parameters, such as the number of input and output system, initial state, the sampling time second stage is the operational phase, the Stages to calculate the output, update the discrete state, continuous calculation of the state, etc., this stage requires repeated runs to the end.)

LMS自适应滤波器做系统辨识，输入为高斯白噪声，可运行，有注释(LMS adaptive filter to do system identification, input Gaussian white noise can be run by a comment)

设计一维纳滤波器 (1). 产生三组观测数据：首先根据S(n)=aS(n-1)+w(n)产生信号S(n)，将其加噪声(信噪比分别为20db，10db，6db)，得到观测数据X1(n)，X2(n)，X3(n)。. (2). 估计Xi(n)，i=1，2，3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L，N对实验结果的影响。(Design a Wiener filter (1) produces three sets of observations: First, according to S (n) = aS (n-1)+ w (n) generates the signal S (n), to add noise (SNR are 20db, 10db, 6db ), obtained observational data X1 (n), X2 (n), X3 (n). . (2) estimated Xi (n), i = 1,2,3 of the AR model parameters. Assuming the signal length L, AR model order N, the analysis of experimental results, and discuss the changes in L, N to the experimental results.)
