Fastattributereduction

This is the code of DEEC protocol of wireless sensor network. It is a matlab code

This program is about short time fourier transform.

通过建立状态空间模型，使用simulink仿真，其中包括了kalman滤波(Through the establishment of the state space model, using the simulink simulation, including the kalman filter)

雷达高斯分布相干视频噪声和高斯分布中频噪声仿真(Coherent Radar Gaussian noise and Gaussian frequency video noise simulation)

CDMA业务信道卷积编码实现，根据上下行信道区分生成不同码率的卷积码序列，original_sequence是原始输入序列，channel_select是信道选择参数，其中下行码率为1/2，上行信道为1/3 (CDMA business channel convolutional coding to achieve, according to the distinction between upper and lower line to generate a different channel bit rate of the convolutional code sequence, original_sequence is the original input sequence, channel_select is channel selection parameters, which downlink bit rate of 1/2, upstream channel for the 1/3)

说明：  计算测地距离，测地距离是众多距离的一种，在高维流行数据分布空间上，欧式距离不再适用，这时就可用到欧氏距离(Computing geodesic distance, geodesic distance is a large distance, popular in high-dimensional data distribution space, the Euclidean distance is no longer applicable, then you can use the Euclidean distance)

matlab ,格林函数 直接求方程零点，取代自洽迭代过程(Matlab, the Green' s function directly demand equation zero, replacing the self-consistent iterative process)

kernel density estimation MATLAB

说明：  支持向量机的matlab实例，对学习支持向量机有很大的帮助。(The matlab example of the support vector machine is of great help to the learning support vector machine.)

this is a code for checkblock
