QPSK
Direct sequence spread spectrum (DSSS) communication systems has been widely
used in these years for its advantage of wide spectrum, low working Signal-to-Noise
ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
They are increasingly replacing conventional communication forms and obtaining
extensively applications in modern military and commercial communication systems,
for example, CDMA communication system, GPS , measuring and control system,
satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS
electronic counter technique becomes a big problem to solve in electronic warfare
domain. DSSS electronic counter technique including blind detection, blind parameter
estimation and spreading sequences estimation. For the issue of DSSS electronic
counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian
noise (AWGN), the main research content in this dissertation as follow.

动态PCA方法，引入动态时间l，考虑变量本身的时序自相关性，同时还分析变量之间的时序相关性,把PCA方法应用到动态数据矩阵。
(Dynamic PCA method, introducing dynamic time l, consider the timing of the variable itself autocorrelation, also analyzed the correlation between the timing variables, the PCA method is applied to dynamic data matrix.)

fcmC
在原始的 fcm 算法基础上，对算法中的聚类数 c 和加权指数 m 给出优选方法，
进而而出了 fcm 参数优选自适应算法，通过人造数据与具有实际背景的数据验证可以看出
该算法是有效的，该算法不但可以自适应的给出最佳的聚类数，而且可以验证聚类的有效性，
达到最佳聚类的目的(Fcm algorithm in the original, based on the number of clustering algorithms and the weighted index m given c preferred method, and then out of the fcm parameter optimization adaptive algorithm, synthetic data and practical background in data validation can be seen that the algorithm is effective, the adaptive algorithm can not only give the best number of clusters, and clustering can verify the validity of the purpose to achieve the best clustering)
