较简单的分级聚类，将一个样本空间分为两类(Relatively simple hierarchical clustering, a sample was divided into two categories)

matlab-hfss脚本文件的编写，含有周期性结构的脚本的编写，这个是之前都没人编写的。(Matlab-hfss scripts, file preparation, containing the preparation of the periodic structure of the script, this is a nobody before written.)

Application of spread spectrum for satellite land mobile systems is difficult in satellite link because of synchronization and providing code or considerable Doppler shift. This is particularly high for LEO satellites. So that, a Doppler shift carrying a frequency in band S can reach to several tens of kHz. To estimate and compensate Doppler, a CW pilot carrier is used. The aim of this study is simulate Doppler frequency estimation using MIMO-OFDM technique. Finally, the proposed algorithm is compared to MMSE algorithm in order to insure its performance.
