Jacobi

说明：  little matlab script but still no error

说明：  充分理解傅立叶变换，直接根据傅立叶积分公式编写，并显示单边，双边谱，对于理解单双边频谱有一定帮助。本程序通过函数与调用来呈现。(Fully understand the Fourier transform, Fourier integral formula directly in accordance with the preparation, and display the unilateral, bilateral spectrum, the spectrum for the understanding of a certain single bilateral help. This procedure with the call to a function.)

分析信号谱峭度根据最相关性，提取敏感频段，进一步分析。(The kurtosis of the signal spectrum is analyzed according to the most relevance, and the sensitive frequency bands are extracted for further analysis.)

FIR低通滤波器，用matlab软件实现(FIR filter using matlab )

说明：  MIMO无线通信系统VBLAST算法的Matlab实现（QR分解）(Matlab realization of a MIMO system using VBLAST method (QR decomposition))

永磁同步电机基侧变流器simlink仿真，可直接运行(PMSM base side converter simlink simulation can be run directly)

此程序用提升法实现第二代小波变换 用的是非整数阶小波变换 采用时域实现,步骤先列后行 正变换：分裂，预测，更新； 反变换：更新，预测，合并 只做一层（可以多层，而且每层的预测和更新方程不同）(This procedure achieved by lifting the second generation wavelet transform with a non-integer order wavelet transform time-domain realization of transformation steps, then over are: split, predict, update inverse transform: Update, forecasting, consolidation only a layer of ( can be multi-layer, and each prediction and update equations are different))

Filterbanks for digital hearing aids must use significantly different criteria than those designed for coding applications. For digital hearing aids, the filterbank channel gains must be adjustable over a large dynamic range to compensate for the hearing loss. This adjustability violates the alias cancellation properties of critically sampled filterbanks designed for coding. This paper describes a filterbank designed exclusively for hearing aid applications. Consideration will be given to the extremely limited memory, low delay and low power requirements that must be met in a typical hearing aid application.

基于BP神经网络的R实现，改进了BP神经网络，可运行。(R implementation based on BP neural network)

说明：  卫星导航与定位中的easy程序：将原始观测数据O-files转换到GPS时间（week+sow）；利用原始观测数据N-files中的时间和星历表计算位置的地心地固坐标；从O-files和N-files获得数据，仅使用伪距，对大于20组的数据进行重复计算，并利用迭代最小二乘法，计算接收机地心地固位置等功能。(Easy program in satellite navigation and positioning: convert the original observation data o-files to GPS time (week + sow); use the time in the original observation data n-files and ephemeris to calculate the geocentric and geocentric coordinates of the location; get the data from o-files and n-files, only use pseudo distance, repeat the calculation of more than 20 groups of data, and use iterative least square method to calculate the receiver geocentric and geocentric Fixed position and other functions.)
