说明：  有偏卡尔曼滤波器可以用来消除无线定位中的非视距误差,本程序加入了非视距检测模块，对于NLOS使用有偏卡尔曼滤波，对于LOS使用标准卡尔曼滤波(Biased Kalman filter can be used to eliminate the wireless location in NLOS error, the program joined the non-line-detection module, for use NLOS biased Kalman filter, using the standard Kalman filter for the LOS)

MATLAB下的四旋翼飞行器建模程序，可以用于仿真四旋翼模型(This is a UAV model under the MATLAB program, The UAV model can be used in the simulation.)

说明：  经典滤波器设计，设置高通、低通、带通滤波器(Classic filter design, set high-pass, low pass, band pass filter)

一个用MATLAB编程的源程序，能实现回响的峡谷效果(a program compiled by matlab,it can produced an effect of canyon reecho.)

matlab的简单小波处理程序，可以进行5层分解，更多层次分解，可以稍作修改 就行。(Simple matlab wavelet processing program, you can break down into five layers, more hierarchical decomposition can be slightly modified on the line.)
