实现对自己录制语音信号的加噪，并设计滤波器对其滤波。(To achieve their own recorded voice signal plus noise, and to design filters for its filter.)

这个是matlab经典教程的一个关于特殊函数的计算的原代码，请大家赶快下载哦，谢谢，(This is a classic tutorial matlab a special function on the calculation of the original code, please download as soon as possible Oh, Thank you,)

主要讲解一些关于matlab的指令 方便大家在使用的时候查找(Explain some of the main directives regarding matlab convenient time for everyone in the use of search)

利用matlab/simulink搭建的简单的发动机模型。(Using the matlab/simulink to build a simple engine model.)

matlab中值滤波源代码，对于图像处理的人员有一定的参考意义。。(median filter matlab source code for image processing personnel have some reference value. .)

说明：  很好用的小波分解程序，简单，对初学者很有帮助。(Nice wavelet decomposition program, for beginners helpful.)

matlab simulink实现DCC滤波器，通信课程设计肯定用的到。(DCC filter matlab simulink realization, communication course design certainly used to.)

说明：  运动载体的定位与导航一般应用Kalman滤波算法。可 靠的Kalman滤波算法要求有可靠的函数模型、随机模型以 及合理的估计方法。实际情况中运动载体一般难以确保规 则运动，因而精确的函数模型的构造十分困难。近年来， 有不少学者对机动载体运动模型进行了讨论，所属内容各 具特点，建立的各种模型包括微分多项式模型、常速度模 型、常加速度模型、时间相关模型，半马尔柯夫模型、 Noval统计模型及机动载体的“当前”统计模型(Moving vehicle positioning and navigation general application of the Kalman filter algorithm. Kalman filter algorithm requires a reliable function model, a stochastic model, as well as a reasonable estimation method. Moving carrier in the actual situation is generally difficult to ensure a regular motion, and thus the the precise function model structure is very difficult. In recent years, many scholars have discussed the movement of the motor carrier model, each with distinct characteristics of their respective content, establish various models including the differential polynomial model, constant velocity model, constant acceleration model, time-dependent model, semi-Markov model, Noval statistical model and motor carrier &quot current&quot statistical model)

陀螺漂移仿真,仿真陀螺漂移误差模型，对于研究惯导陀螺误差有一定帮助(Gyro drift simulation gyro drift error model for the study of inertial gyro error of some help)
