覆盖保存是WSN的一个基本质量要求。选择一个最佳的簇头，以满足长时间的监视区域的完全覆盖。使用覆盖意识的方法来选择簇头，而不是基于能量的方法，可以增加场景有效时间。(WSN coverage preservation is a basic quality requirements. Choose one of the best cluster head in order to meet long surveillance area completely covered. Awareness of the methods used to select the cover cluster head, rather than energy-based method, can increase the effective time of the scene.)

经典MUSIC算法，带有空间前向平滑功能(Classical MUSIC algorithm with spatial smoothing function )

基于支持向量机算法的分类程序，matlab实现。(Based on support vector machine algorithm for classification procedures, matlab realize.)

HHT变换中用于边际谱与FFT比较的一个源码。本人亲试，出的图形基本满足要求。你可以下来看看。(HHT marginal spectrum for the transformation of a source compared with the FFT. I pro-test, the graphics basically meet the requirements. You can look down.)

说明：  这种是一个评价方法 可以用来评价较为客观公正(This is an evaluation method, which can be used for evaluation, which is objective and fair)

It contains the matlab simulation for the Grid connected fuel cell

速度分析，形成速度谱，加入了各向异性参数(Velocity analysis, the formation of the velocity spectrum, joined the anisotropy parameter)

dpsk信号的调制解调matlab代码实现的一个例子，采用正交调制解调。(DPSK signal modulation and demodulation matlab code an example of the use of orthogonal modulation and demodulation.)
