这个matlab程序,按照节点的能量把选举成为簇头的概率分为了两种,能量高的,概率大,这样就总体的延长了节点群的生存时间(The matlab program, in accordance with the energy of the node to elect the cluster head of the probability is divided into two kinds, high energy, the probability is large, so that the overall extension of the node group s survival time)

this source code based on steganography and developed in matlab. in steganography we can hide any data like images in another image. this method based on discrite fourier transform method.

说明：  一种核密度估计，或者称作带宽选择的方法，可以估计二维尺度参数，至于多维以上的估计方法尚在开发，多维情况下个人经验好的方法是多次实验取较好值(kernel density estimation, bandwidth selection, two-dimensional scale parameter can be estimated ,for the multi-dimensional approaches are still under development, multi-dimensional cases, personal experience is to do the experiment many times)

说明：  双门限算法，用于语音端点检测。可以通过调整门限值，并加入门限自适应算法，实现语音端点检测。(double door ,speech endpoint detection two games adjust itself)

关于matlab各种指令用法及汇总，很适于初学者使用。(image processing)

将压缩感知用于谱估计中，根据论文谱压缩感知的一些程序(Compressive sensing (CS) is a new approach to simultaneous sensing and compression of sparse and compressible signals based on randomized dimensionality reduction. To recover a signal from its compressive measurements, standard CS algorithms seek the sparsest signal in some discrete basis or frame that agrees with the measurements. A great many applications feature smooth or modulated signals that are frequency sparse and can be modeled as a superposition of a small number of sinusoids. Unfortunately, such signals are only sparse in the discrete Fourier transform (DFT) domain when the sinusoid frequencies live precisely at the center of the DFT bins. When this is not the case, CS recovery performance degrades significantly. In this paper, we introduce a suite of spectral CS (SCS) recovery algorithms for arbitrary frequency sparse signals. The key ingredients are an over-sampled DFT frame, a signal model that inhibits closely spaced sinusoids, and classical sinusoid parameter e)
