计算阿兰方差，为matlab计算阿兰方差函数(Allan variance)

by Usman Haider This blockreceives serial data from an instrument or processor and decode it to apply on a plant model. You can see how serial receive block works and other blocks like ASCII Decode and Data type conversion . After receiving the data and decoding, it is applied to the plant model (transfer function of the plant). You can see the realtime plant response on oscilloscope block. Out put of various stages is recorded in workspace which can be examined after the simulation. The reader can learn interfacing hardware to the simulink by going through settings of serial configuration block and serial receive block. God knows the best.

1. 选择一个wav文件作为分析的对象，对该信号进行读取（使用wavread函数）； 2. 音乐信号的频谱分析：首先画出信号的时域波形，然后对信号进行频谱分析得到信号的频谱特性。 3. 设计一组数字滤波器并画出各个滤波器的频率响应 (Filter)

语音的端点检测 噪声可以自己加 使用阈值进行检测 能量的阈值跟据经验来进行决定(Speech endpoint detection noise can add to the threshold detection energy threshold according to experience to the decision)

雷达sar成像的距离多普勒算法的仿真测试，进行径向脉冲压缩的测试(range doppler algorithm test)

一些自适应信号处理的算法，包含特征值与特征向量的提取、训练样本以及最后的识别，进行波形数据分析,是路径规划的实用方法，能量熵的计算，Matlab实现界面友好，数值分析的EULER法。( Some adaptive signal processing algorithms, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Waveform data analysis, Is a practical method of path planning, Energy entropy calculation, Matlab to achieve user-friendly, EULER numerical analysis method.)
