仿真信号的FFT频谱和功率谱，绘制了emd分解结果，以及瞬时包络和瞬时频率图，还有Hilbert-Huang谱和Hilbert边际谱。(The FFT spectrum and power spectrum of the simulated signal, the emd decomposition results, and the instantaneous envelope and instantaneous frequency maps, as well as the Hilbert-Huang spectrum and the Hilbert marginal spectrum.)

托普利兹MUSIC算法，一个信号源，仿真通过(toeplitz_music)

This is a code for comparison of 2-PAM, 4-PAM and 8-PAM. Generates a graph of each of the PAM on same figure, easily comparable. Code of 2,4 and 8-Pam included.

说明：  神经网络BP辨识的Matlab算法，用于辨别复杂的非线性系统(Identification of the Matlab neural network BP algorithm, used to identify the complex nonlinear systems)

使用自适应中值滤波器对图像做预处理，实现图像的消噪(Use adaptive median filter to the image preprocessing, to achieve image denoising)

Adaptive filter algorithms, contour plots and weight convergence

《计算物理基础》是北师大彭老师写的，对学习用matlab解决物理问题很有帮助(this is a book about Computational Physics used matlab,the author is Mr peng and come from Beijing Normal University)

QPSK调制 经典，非常简洁的产生qpsk的调制方法1(QPSK Modulation)

说明：  使用iwr16xx雷达板进行人体摔倒检测(Fall detection, useTI iwr16xx board)

说明：  burg算法求功率谱,用matlab实现,其中用到了arburg和pburg等函数(burg algorithm for power spectrum, with the realization of matlab, which uses a function such as arburg and pburg)
