说明：  实现4psk调制的源程序，以及对应的在白噪声信道下的系统性能(achieve 4psk modulation source, as well as corresponding white noise in the channel system performance)

Albert-László Barabási与Réka Albert在1999年的论文中提出了一个模型来解释复杂网络的无标度特性，称为BA模型。这个模型基于两个假设： 增长模式：不少现实网络是不断扩大不断增长而来的，例如互联网中新网页的诞生，人际网络中新朋友的加入，新的论文的发表，航空网络中新机场的建造等等。 优先连接模式：新的节点在加入时会倾向于与有更多连接的节点相连，例如新网页一般会有到知名的网络站点的连接，新加入社群的人会想与社群中的知名人士结识，新的论文倾向于引用已被广泛引用的著名文献，新机场会优先考虑建立与大机场之间的航线等等。 (Albert-László Barabási with Réka Albert in the 1999 paper proposed a model to explain the complex networks of scale-free property, known as the BA model. This model is based on two assumptions: Growth pattern: a lot of real network is expanding growing from, for example, the birth of the Internet BEIJING, page, new friends to join the network of people, a new paper published aviation network in the new airport construction and so on. Priority connection mode: a new node upon accession will tend to connect to the node connected to, for example, a new page will generally have a connection to the well-known networking sites, and the new Community will want with the community s well-known get to know the new paper preference is to use well-known literature has been widely cited, the new airport will give priority to create and airport routes.)

基于EKF的参数估计算法理论，这是个英文文献，主要介绍了用EKF方法去识别结构的参数。(The parameter estimation algorithm based on EKF theory, this is English literature, introduces the parameters EKF method to identify structures.)

该程序是对OFDM信号的频谱感知的循环特征检测方法，代码齐全，介绍详细(The program is the OFDM signal spectrum sensing cycle of feature detection, code complete, detailed description)

计算时间序列的Hurst系数有许多方法，但是其中最准确的就是利用小波法来计算，本程序用Matlab实现了用小波来计算Hurst系数。(Calculation of the Hurst coefficient of time series has a number of ways, but one of the most accurate method is to use wavelet basis, the procedures used to achieve the use of Matlab to calculate the Hurst coefficient of wavelet.)

说明：  用MATLAB编写的空间矢量SVPWM仿真，效果很好(Prepared using space vector SVPWM MATLAB simulation, good results)

stanford大学开发用于解优化问题的系统模型，可用于解压缩感知恢复算法：BP、DS等(the system modeldeveloped by stanford University is used for the solution of optimization problems, such as compressive sensing recovery algorithm: BP, DS)

此程序能够完成对电容元件的几何特性自适应测量。(This program can complete the adaptive measurement of geometric characteristics of the capacitor element. )
