自己编写的一种快速均值漂移聚类算法。数据需要自己下载，里面有main函数,改成自己的数据就可以运行。主要思路是先用近邻规则粗分类，在运行均值漂移。(fast mean shif clustering algorithm.)

最新版的matlab gauge工具箱，目前很多版本无法自带安装，直接解压后添加到toolbox目录下即可（附带很多有用控件）(The latest version of matlab gauge toolbox, many versions of currently installed not own, directly unpacked directory can be added to the toolbox (with a lot of useful controls))

在MATLAB中建立基于VSG控制方法下的孤岛模式下带负载稳定运行(The load stable operation with VSG control based on the island)

This paper examines the asymptotic (large sample) performance of a family of non-data aided feedforward (NDA FF) nonlinear least-squares (NLS) type carrier frequency estimators for burst-mode phase shift keying (PSK) modulations transmitted through AWGN and flat Ricean-fading channels. The asymptotic performance of these estimators is established in closed-form expression and compared with the modified Cram`er-Rao bound (MCRB). A best linear unbiased estimator (BLUE), which exhibits the lowest asymptotic variance within the family of NDA FF NLS-type estimators, is also proposed.

说明：  QPSK调制的Matlab程序。包含了QPSK调制及误码率分析。可以调制一随机产生的序列来分析误码率，也可以调制一幅图像来分析误码率。(QPSK modulation of the Matlab program. Contains a QPSK modulation and BER analysis. Can be modulated to a randomly generated sequence analysis of BER, an image can also be prepared to analyze the error rate.)

通过matlab编程实现了通信原理中的模拟频率调制（FM)，并画出了波形。(this source code can realize the fm modulation in communication principles.)

主成分分析的代码，数据处理的必备，方便实用！！(Principal component analysis of the code, the data processing required, convenient and practical! !)
