本程序完成地震信号的提取检测。以往都是利用地震信号的能量比，此处创新选择地震信号的过零点作为边缘提取的判断。新方法效果不错。(The process is complete extraction of seismic signal detection. Past, the energy ratio of seismic signal, where innovation and choice as the seismic signal zero-crossing edge detection judgments. The new approach is very effective.)

本算法能够按照两种策略生成并绘制随机图，但是对于生成的随机图的属性分析不够完善，从代码中能够看出作者并没有完成本算法关于“平均路径长度”、“聚类系数”和“平均度”三个属性的求解。(The algorithm is able to follow two strategies to generate and draw random graph, but for the properties generated random graph analysis is not perfect, it can be seen from the code of the algorithm is not complete on the "average path length", "clustering coefficient" and "the average degree of" solving the three properties)

This M Code simulate the effects of clipping and filtering on PAPR PAPR reduction in OFDM-based wireless standard.Also the performance of BER versus SNR of original OFDM signals with PAPR reduction based on clipping and filtering schemes over AWGN channel is evaluated. The simplest and most widely used technique of PAPR reduction is to basically clip the part of signals that are outside the allowed region.Clipping methode introduces both in band distortion and out of band radiation into OFDM signals which degrades the performance including the BER and spectral efficiency.Filtering can reduce out of band radiation after clipping although it can not reduce in-band radiation distortion.However, clipping may cause some peak regrowth so that the signal after clipping and filtering will exceed the clipping level at some point.To reduce peak regrowth a repeated filtering and clipping operation can be used to obtain a desirable PAPR at a cost of computational complexity increase.
