迭代自组织数据分析，是本科毕设的题目，使用高阶累积量对MPSK信号进行调制识别。( Iterative self-organizing data analysis, The title of the commercial is undergraduate course you Using high-order cumulants of MPSK signal modulation recognition.)

MATSLISE is a Matlab application for the numerical study of Schringer and Sturm-Liouville problems. MATSLISE allows one to compute the eigen- values and eigenfunctions and to display them graphically. The numerical methods used are the CP methods (abbreviation for Constant reference potential Pertubation Method).

克里格法是地统计学的主要内容之一，从统计意义上说，是从变量相关性和变异性出发，在有限区域内对区域化变量的取值进行无偏、最优估计的一种方法；从插值角度讲是对空间分布的数据求线性最优、无偏内插估计一种方法。(Kriging method is one of the main contents of geostatistics. Statistically speaking, it is a method of unbiased and optimal estimation of regionalized variables in a limited area from the point of view of correlation and variation of variables; from the point of view of interpolation, it is a method of seeking linear optimum and unbiased interpolation estimation of spatial distribution data.

从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力，进行实验仿真，比较不同的窗函数，不同的数据长度对Welch法谱估计质量的影响，并分析了造成这些影响的原因。(The paper mainly introduces the principles of Periodogram method of classical PSD estimation,analyzes the deficiency of Periodogram method in theory,and makes use of Welch to amend Perodogram method. By the use of simulation in Matlab, the impacts of different window function and different lenghth of data on estimation quality of Welch are discussed and the reasons of the impacts are analyzed.)
