多元数据分析的主分量分析投影，esprit算法对有干扰的信号频率进行估计,能量谱分析计算。( Principal component analysis of multivariate data analysis projection, esprit algorithm signal frequency interference can be assessed Energy spectrum analysis and calculation.)

负向选择算法的一个例子,它的基本思想就是通过采集正常数据集合生成检测器集，然后将待测数据与抗体集合中全部元素进行匹配计算，如与任一元素的匹配达到一定阈值，即判断该数据异常。(An example of negative selection algorithm. The basic idea is to collect the normal data set generated by the detector set, and then tested the data collection with the antibody to match all the elements of calculation, if any element of the match reaches a certain threshold, that determine the data exception.)

此程序为8cpfsk的同步部分用msk实现(This program is part of 8cpfsk synchronization achieved by msk)

本人自己做的功率谱估计的课程作业，利用matlab实现古典和现代功率谱估计，有间接法，burg法，music法。完全一步一步实现的，希望对大家有帮助(Course work, I do own the power spectrum estimation using matlab classical and modern power spectrum estimation, the indirect method, burg, law, music law. Full step by step, we hope to)
