说明：  刚刚接触神经网络的朋友们看了这本书会有一定得帮助的！！(Neural network has access to friends read this book will have to help! !)

基于频带方差的语音端点检测，很有用的，大家自己好好看，不是太难(variance based on the frequency of speech endpoint detection, very useful, we all do well, not too difficult)

：随着无线技术的飞速发展，频谱缺乏已经成为一个非常严重的问题．感知无线电技术能有效解 决频谱紧张的现状．介绍了感知无线电概念及其内涵，然后介绍了检测频谱空穴的方法．为提高检测概率、 降低设备复杂度及计算复杂度，将UWB与感知无线电结合，提出了基于能量检测及用户合作（EDAUC）的 协作感知方法．仿真和分析表明：该方法能有效提高检测频谱空穴的概率．(: With the rapid development of wireless technology, the lack of spectrum has become a very serious problem. Cognitive radio technology can effectively solve the spectrum tense situation. Introduced the concept of cognitive radio and its content, and then introduces the method of detection of spectrum holes. To improve the detection probability and reduces the complexity and computational complexity, the combination of UWB and cognitive radio is proposed based on energy detection and user cooperation (EDAUC) the cooperative sensing methods. Simulation and analysis: This method can improve the probability of detection of spectrum holes.)

在程序中将不相干的一些数据进行处理,并用mschart绘制出直观图出来(procedures will be irrelevant in some of the information processed and used mschart drawn out direct-viewing chart)

一个KKV标准弹道仿真程序，仿真了KKV在中段拦截TBM的弹道。供大家参考。下面还会上传其他方法仿真的程序。(KKV standard ballistic simulation program, the simulation of KKV in the middle of the TBM interception trajectory.For your reference.The following simulation program also upload other methods.)
