electric field of bragg reflectivity waveguide

说明：  匹配追踪算法的matlab工具箱，可以比较方便的进行mp分解，效率较高，但目前的版本对于谐波原子的分解还有些问题(Matching pursuit algorithm matlab toolbox, can be more convenient mp decomposition, efficient, but the current version of the harmonic decomposition of the atom has some problems)

说明：  稀疏的牛顿法潮流程序，谢谢。请下载使用。(Sparse Newton Flow program, thank you. Please download.)

这是一个矢量水声器测量。方向的小程序，希望对大家有用(This is a vector hydrophone measurements. The direction of a small program, we hope to be useful)

设计音频降噪算法，并用MATLAB仿真实现。 1）读入一段音频后添加噪声，必须包括两种不同的噪声，信噪比：0dB~10dB； 2）分别采用滑动平均滤波器，直接频域滤波，以及谱分析后设计滤波器滤波三种方法实现，并对比效果。 3）给出各种方案的设计依据、代码、频响曲线，以及输入输出对比图。(Audio noise reduction algorithm design, and use MATLAB Simulation. 1) Read after adding noise into an audio, it must include two different kinds of noise, SNR: 0dB ~ 10dB 2) respectively moving average filter directly in the frequency domain filtering, and the filter is designed to achieve three methods filter after spectral analysis and contrast. 3) Give the design basis, code, frequency response curve, and input and output comparison chart of the various programs.)

捷联式惯性导航的角速率匹配卡尔曼滤波，使用matlab语言编写(Strapdown inertial navigation of angular rate matching kalman filter)

说明：  基于负熵的盲源分离算法，可以用于语音的盲分离，提高语音信号质量。本代码中，对原始信号分别为正弦波，方波，和随机信号，通过高斯信道的混合矩阵，获得接收信号，并通过基于负熵的盲源分离算法分理处原始信号。PS：Matlab版本为2018Ra(The blind source separation algorithm based on negative entropy can be used for speech blind separation and improve the quality of speech signal. In this code, for the original signal, sine wave, square wave and random signal, the received signal is obtained through the mixture matrix of the Gauss channel, and the original signal is processed by the blind source separation algorithm based on negative entropy. PS: MATLAB Version 2018Ra)
