Extended Kalman Filter Tracking Object in 3-D(Assume that we want to track an object moving in 3-D space with constant velocity. Our instruments observe bearing, range and high(cylindrical coordinates). However, of an interest are rectangular coordinates. Since transformation is non-linear this requires use of extended Kalman filter. Because transformation is non-linear between X,Y and Range,Bearing and linear between Z and high(Z is height), this problems serves as a good comparason of how well extended Kalman filter can perform. By comparing its linear estimation error in Z to non-linear estimations in X and Y, we can judge how non-familiarities effect estimation. )

steady state short circuit calculation

说明：  本程序为利用matlab求解微分方程的源程序及相关例子.(matlab.)

说明：  压缩文件夹中包含二十几个ＭＡＴＬＡＢ编写的仿真程序，包括ＧＭＳＫ信号的调制仿真，ＰＮ码生成，ＦＩＲ滤波器的设计，ＧＯＬＤ序列的生成等等，另外还有许多经典的滤波器变换的小程序(compressed file folder containing 20 prepared by several MATLAB simulation program, including GMSK modulation signal simulation, PN code generation, FIR filter design, GOLD sequence generation, etc., in addition to many classic filter transform small program)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

这是基于matlab编写的一套用于指纹识别的源码，可以即得即用，很是详细。(This is based on the preparation of a set of matlab source code for fingerprint recognition, which you can get that is used, it is detailed.)

说明：  常规AM调制：画出调制前波形图和频谱图 求已调信号功率、噪声功率等(Conventional AM modulation: Draw modulation waveform and spectrum before seeking modulated signal power, noise power, etc.)

在完成gps信号跟踪之后，进行接收机的位置解算。得到接收机的正确位置。(After the completion of gps signal tracking, the receiver of the positioning solution. Get the correct position of the receiver.)
