The Rö ssler attractor /ˈ rɒ slə r/ is the attractor for the Rö ssler system, a system of three non-linear ordinary differential equations originally studied by Otto Rö ssler.[1][2] These differential equations define a continuous-time dynamical system that exhibits chaotic dynamics associated with the fractal properties of the attractor.

这事我用巴特沃斯模拟的方法设计的数字低通，高通，带通滤波器，其中只有一小段(I used this method to design analog Butterworth digital low pass, high pass, band pass filter, which only a short)

设计一维纳滤波器。 （1）产生三组观测数据，首先根据s(n)=as(n-1)+w(n)产生信号s(n)，将其加噪(信噪比分别为20dB，10dB，6dB)，得到观测数据x1(n)，x2(n)，x3(n)。 （2）估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L，N对实验结果的影响。 (Design a Wiener filter. (1) generate three sets of observations data, first according to s (n) = as (n-1)+w (n) to generate a signal s (n), which add noise (SNR respectively 20dB, 10dB, 6dB), obtained observation data x1 (n), x2 (n), x3 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss changes affect L, N of the experimental results.)

matlab的一些雷达信号仿真程序，很有用的！(some matlab radar simulation program, very useful!)

说明：  利用MATLAB模拟二维海浪，直接运行即可。简单好用。(Using MATLAB to simulate two dimensional sea waves, it can run directly. It's easy to use.)

一个很小手势识别工具. 这是我读Master的时候一个小作业. 我是用block FFT 来写的.70 -80 识别率.(A gesture recognition tool.It was a modle assigment, when I was doing my Master degree. I used block FFT. The recognition rate is round 70-80 )
