PTFT

例子滤波的源代码,很基础，便于初学者学习粒子滤波 (Filtering source code examples, very basic, easy for beginners to learn particle filter)

高斯平滑滤波，属于低通滤波，有效去除图像噪声。(Gaussian smoothing filter, a low pass filter effectively removes image noise.)

交通标志检测 根据输入图像检测标志信息(traffic sign)

I have included a code to generate 3d model of DEM in Matlab. It also has the DEM data.

本程序的功能是将模型结果直接输出到excel中的演示(The program s function is to generate the result of the model to demonstrate in excel)

对多径信道的仿真 输入码元,是一行矩阵,可以是实数也可以是复数 ％fs是输入码元的比特率 ％fd是多普勒频移 ％n_delay是多径信道的径数 ％t_delay是多径信道各径的时延时间 ％p_delay是多径信道各径的功率db值 (Of the multipath channel simulation input symbol is a line matrix, can be a real number can also be plural fs is the input symbol of the bit rate fd is the Doppler frequency shift is n_delay multipath channel diameter of a few t_delay is multipath channel time delay of the Path p_delay is multi-path channel the power of the diameter db value)

说明：  系统参数辨识，用增广最小二乘算法实现。对书中的程序进行了改进：由于噪声是未知的，虽然我们模拟了系统的随机白噪声，但进行辨识时必须对噪声进行估计，见程序45行和53行。(System parameter identification, with the extended least squares algorithm. Procedures for improving the book: Because the noise is unknown, although we simulate a system of random white noise, but to identify the noise must be estimated, see the program of 45 lines and 53 lines.)
