几何活动轮廓模型（snake模型）中level-set算法的matlab源码(Geometric active contour model (snake model) in the level-set algorithm matlab source)

AGILENT关于OFDMA设计的难得的参考资料(This application note is a guide to effective measurement and troubleshooting of IEEE 802.16e OFDMA “Mobile WiMAX” signals, components, and systems. The most distinctive term used to describe this new technology is OFDMA or orthogonal frequency division multiple access, and therefore we will use the term OFDMA in this note as a compact reference to the signal and its associated standard.)

在matlab环境下编写的非线性控制工具箱,希望对大家有用(Written in the matlab environment, nonlinear control toolbox, we hope to be useful)

《现代通信系统》Matlab源程序,一共10章的内容，好东西分享("modern communications systems" Matlab source, a total of 10 chapters, sharing the good things)

输入信号五个基于瞬时信息的特征：零中心归一化瞬时幅度功率谱密度的最大值,零中心归一化瞬时幅度绝对值的标准偏差，零中心非弱信号段瞬时相位非线性分量绝对值标准偏差，零中心非弱信号段瞬时相位非线性分量标准偏差，零中心归一化的非弱信号段瞬时频率绝对值的标准偏差，得到识别出的信号类别，本例为2PSK, 4PSK, GMSK, OQPSK, pi/4DQSK中的一个，还可以看Art网络的扩展性。(input signal instantaneous information on five characteristics : In the center is one of the instantaneous rate of the power spectral density of the maximum, is a center to the absolute value of the instantaneous rate of the standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component absolute standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component standard deviation, In the center is one of the non-weak signal of the absolute value of the instantaneous frequency standard deviation, the identification of signal type, The cases of two PSK, 4PSK, GMSK, OQPSK, pi/4DQSK of one, Art can be viewed network scalability.)

地震数据通常含有噪音，通过该方法可以去除地震数据中的噪音，更好的反演结果(Seismic data usually contains noise, the method can remove the noise in the seismic data, better inversion results)

说明：  关于层次分析的MATLAB源程序，对数学建模求解层次分析问题特别有用。(MATLAB-level analysis on the source of mathematical modeling to solve the issue of the level of analysis particularly useful.)

说明：  这是一个地震波正演的程序，采用雷克子波，可以画出地震的变面积图(use ricker wavelet to do the forward of the seismic)

利用射线追踪的原理实现模型的正演，模拟出地震记录(Ray tracing using the principle of forward implementation model to simulate the seismic records)

是经验模态的函数，用于进行数字信号处理。可以用于分解频率(Is the empirical mode of function, used for digital signal processing. Can be used to decompose the frequency)
