用于5自由度质量已知的结构系统识别，智能计算引入土木工程领域(FOR IDENTIFICATION OF A STRUCTURAL SYSTEM OF 5 DOFS WITH MASS KNOWN.)

一阶扩展卡尔曼滤波，二阶扩展卡尔曼滤波，和Rauch - tu - Striebel平滑器(Perform Extended Kalman Filter prediction step. Extended Kalman Filter measurement update step. Extended Rauch-Tung-Striebel smoother algorithm. Calculate "smoothed" sequence from given Kalman filter output sequence by conditioning all steps to all measurements.)

Comparison with ground truth and triangulation provided, with varying amounts of gaussian noise added in train and test data. GUI is in Portuguese, but self-explanatory. English version will be provided soon.

MATLAB程序，用小波变换的方法实现Haar分解与重构。(MATLAB program, the method used to achieve Haar wavelet transform decomposition and reconstruction.)

自己编写的一种快速均值漂移聚类算法。数据需要自己下载，里面有main函数,改成自己的数据就可以运行。主要思路是先用近邻规则粗分类，在运行均值漂移。(fast mean shif clustering algorithm.)

清华张旭东老师《离散随机信号处理》教材第5章。本章首先简要复习经典谱估计的基本结论，然后分别讨论基于线性系统模型和复正弦模型的功率谱估计方法。(Qinghua Zhang Xudong teacher " discrete stochastic signal processing" textbook Chapter 5. This chapter begins with a brief review of the classical spectral estimation basic conclusion, and then discuss the power spectrum estimation based on linear system models and complex sinusoidal model approach.)

说明：  实现IIR的算法，包括数据分析报告，Matlab实现巴特沃思和切比雪夫。(To achieve IIR algorithms, including data analysis, Matlab realization of Butterworth and Chebyshev.)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter. (M-file for simulating a QPSK transmitter b y modulating with a pseudo random bit stream.
