小波包分析提取振动信号中的特征频率，可以动态调节运行环境的参数，sar图像去噪的几种新的方法。( Wavelet packet analysis to extract vibration signal characteristic frequency, Can dynamically adjust the parameters of the operating environment, Several new methods sar image denoising.)

说明：  CFAR代码，CFAR是用于雷达的一种滤波方法，称为平均值滤波，本程序给出了主程序以及CFAR-function，并且有噪音图和信号图，可以进行比较分析(CFAR code, CFAR radar for a filtering method, known as average filtering, the process is the main program and CFAR-function, and the noise and signal map plan, it can conduct a comparative analysis)

说明：  这是MPM算法，用MATLAB实现的，需要简单修改一下。这个对于mkv算法的实现是很重要的。(This is the MPM algorithm, using MATLAB to achieve, requires simple corrections. Mkv algorithm for the realization of this is very important.)

this is matlab codes

pure aloha 和slotted aloha算法的 matlab代码。结果显示了两种算法吞吐量的对比，通过修改标签数也可以得出吞吐量的变化值。 纯ALOHA协议(Pure ALOHA) 当传输点有数据需要传送的时候，它会向立即向通讯频道传送。 接收点在收到数据后，会ACK传输点。 如果接收的数据有错误，接收点会向传输点发送NACK。 当网络上的两个传输点同时向频道传输数据的时候，会发生冲突，这种情况下，两个点都停止一段时间后，再次尝试传送。 因为有太多的传输冲突.(pure aloha and slotted aloha algorithm matlab code. The results show the comparison of the two algorithms throughput, by modifying the number of labels can also come to change the value of the throughput. Pure ALOHA protocol (Pure ALOHA) When the transfer point has data to transmit, when it would have to immediately transfer to the communications channel. After receiving the data reception point will ACK transmission points. If the received data has an error, the receiver sends NACK point to point transmission. After transmission when two points on the network at the same time to the channel to transmit data, it will conflict, in this case, two points are stopped for some time, try the transfer again. Because there are too many transmission conflict.)

Matlab控制系统应用实例，包含50多个实例(Matlab control systems application examples, including more than 50 examples of)

针对无刷直流电机的特性，使用simulink库模块进行反电动势控制仿真。(According to the characteristics of Brushless DC motor, the back EMF control simulation by using Simulink module.)

it is about ldpc codes

说明：  人工蜂群算法(Artificial Bee Colony, ABC)是由Karaboga于2005年提出的一种新颖的基于群智能的全局优化算法，其直观背景来源于蜂群的采蜜行为，蜜蜂根据各自的分工进行不同的活动，并实现蜂群信息的共享和交流，从而找到问题的最优解。对原始算法的改进。(The improvement of the original Artificial Bee Colony.)

k均值的 咱们做非监督分类都用过 不想理解他的原理吗 很重要(k mean we do not want unsupervised classification are used to understand his theory is very important to you)
