产生QPSK信号，根据仿真的数据估计差错概率(Produce QPSK signal and estimate the data according to the error probability)

说明：  许树柏著的层次分析法原理一书，非常经典，PDF 版(Xu Shubai the principle of AHP, a book is very classic, PDF version)

宇航工具箱，包括地影计算、大气密度计算等(Aerospace Toolbox, including the shadow calculation, calculation of atmospheric density)

一个计算线性支持向量机的matlab源代码，台湾人编写，在c环境下运行(A calculation of the linear support vector machine matlab source code, the people of Taiwan to prepare, in the c environment running)

说明：  用MATLAB编程实现半导体光放大器（SOA）的ASE噪声特性分析，可以计算半导体光放大器的载流子密度，ASE增益，噪声指数，主要用的是半波逼近法来实现数值算法。(Programming with MATLAB semiconductor optical amplifier (SOA) of the ASE noise characteristics analysis, semiconductor optical amplifiers can calculate the carrier density, ASE gain, noise figure, the main use is half-wave approximation method to achieve the numerical algorithm.)

实现LS信道估计的算法，很好的算法，对初学者有很大帮助(LS_MMSE_channel_estimators_for_OFDM)

matlab的文档，想要学习matlab的同学可以看看。(The people who wants to learn the Matlab well can download the PDF documents.)
