说明：  任意阵列输出数据的协方差进行奇异值分解，求出特征值和特征向量，利用信号子空间和噪声子空间的正交性，构造空间谱函数(Arbitrary array output data covariance singular value decomposition, eigenvalues and eigenvectors obtained using the signal subspace and noise subspace orthogonality spectral function space constructor)

分析并实现了奇异谱斜率，并把它用到频段的信号检测中(Singular spectrum analysis and implementation of the slope, and put it to use in-band signal detection)

用Matlab语言编写的实现fisher准则，可以很方便的验证fisher准则(Fisher guidelines for implementation of the Matlab language, you can easily verify that the fisher criteria)

发个Arnold置乱变换的matlab代码(Arnold matlab)

Triangle numbers are the sums of successive integers. So 6 is a triangle number because 6 = 1 + 2 + 3

这是一个用simulink编程，可以来实现QAM，里面有多个程序，如果毕业设计是关于这个内容的，可作为参考(This is a simulink programming, can come to realize QAM, there are a number of procedures, if the graduation project is on the content, may be used as reference)

文章运用分级抽取和多相滤波的方法改进传统CIC滤波器的结构,降低了系统工作频率,运用幅度改进函数(ACF)和外加级联余弦预滤波器的技术改进了滤波器频率响应,提出了一种高效的算法结构,改善了通带损耗,增大了阻带衰减,对CIC滤波器的实际应用和深入研究有着现实意义。 (Article the use of hierarchical multi-phase extraction and filtering methods to improve the structure of the traditional CIC filter, reducing the system operating frequency, the use of margin to improve the function (ACF) and the cosine cascade plus pre-filter technology to improve the filter frequency response, the an efficient algorithm to improve the pass-band loss, increases the stopband attenuation of the CIC filter in practical applications and in-depth study has practical significance.)

一个学习matlab的课件，对于新入门的学习者比较有帮助(Matlab a learning courseware, the new entry for more helpful to learners)

本文针对基于经验模态分解ＥＭＤ的时空滤波器存在的固有模态函数分量中频率混叠交叉导致有用信号与噪声一起被滤除的问题结合小波在时间尺度两域表征信号局部特征的特性提出了一种基于能量估计实现ＥＭＤ分解层数确定(In this paper, based on empirical mode decomposition EMD temporal filter mode functions inherent component of cross-frequency aliasing and noise together lead to useful signal is filtered in the time scale of the problem combined with wavelet domain characterization of two local features of the signal characteristics of proposed achieve energy estimation based on EMD decomposition level determined)
